Jake the Dog
Finn's adoptive brother and best friend. A 28-year-old dog with magical stretching powers from his alien heritage.

Episodes
A trip through 10 seasons, 283 episodes, and a few Distant Lands specials.
World of Ooo
A candy kingdom, an ice kingdom, a fire kingdom, and a whole lot of mushroom wars.
Legacy
Why this show about math, candy, and feelings became a generational touchstone.
Characters of Ooo
The main cast, the rulers, the allies, and the troublemakers. Adventure Time is a character study disguised as a candy-colored cartoon.
THE CORE CREW
Last known human in Ooo. A 13-year-old (later 17) adventurer with the sword Finn Sword, a backpack full of stuff, and an unshakable sense of justice. Adopted by Joshua and Margaret as a baby after the Mushroom War.
Finn's adoptive brother, age 28 (magical dogs age differently). His alien father Warren Ampersand gave him the power to stretch and reshape his body. Wise, laid-back, but fiercely loyal.
Bonnie. A sentient candy being, ruler of the Candy Kingdom, and a genius scientist. Created from bubblegum during the Mushroom War to oppose the vampires. Equal parts loving monarch and ruthless protector.
A 1,000+ year old vampire, the Vampire Queen's daughter, and a legendary musician. Half-demon, plays an axe-bass, and has the most complicated relationship with Ice King (Simon Petrikov).
FRIENDS, ROYALS & ANTI-HEROES
Once a kind archaeologist, the crown warped his mind. Tragic backstory revealed in "Simon & Marcy" and "I Remember You." Became a complex ally in later seasons.
A living video game console, Finn and Jake's roommate, and possibly the purest character in the show. Plays soccer with a ball, fights evil, and makes great art.
Created by Princess Bubblegum from a lemon candy. Now Earl of the Candy Kingdom and ruler of his own lemon estate. Loyal to his subjects, impatient with everyone else.
The noble soldiers of the Candy Kingdom, dressed in banana suits. Loyal, surprisingly competent, and comedic in all the right ways. "The Banana Guard stands strong."
Episodes & Seasons
From a 7-minute pilot about a boy and his dog to a four-part series finale. Adventure Time ran on Cartoon Network from April 5, 2010 to September 3, 2018, with 10 seasons, 283 episodes, and a film-quality finale.
Season 1 — "Slumber Party Panic"
The first season introduces the world. Finn and Jake's Tree Fort, Princess Bubblegum, the Candy Kingdom, Ice King, and the very first "Fionna and Cake" flickers. It's all weird, colorful, and full of rapid-fire gags.
Season 2 — "It Came from the Nightosphere"
Marceline gets a fuller introduction. The show starts taking emotional risks alongside its comedy. "The Eyes," "Susan Strong," and the haunting "A Glitch is a Glitch" expansion.
Season 3 — "The Conquest of Cuteness"
More worldbuilding: Marceline's past, the Ice King's loneliness, Jake's alien origins hint. Episodes begin transitioning from standalone to serialized storytelling.
Season 4 — "Hot to the Touch"
The Fire Kingdom arrives. "Lady & Peebles" gives us a buddy episode. "I Remember You" — the show's most beloved musical gut-punch — lands in this season.
- "I Remember You" — Marceline and Ice King (Simon) sing a song they wrote together before he forgot her. 11 minutes of pure heartbreak.
Season 5 — "Finn the Human"
PBS-adjacent storytelling begins. "Simon & Marcy" reveals Ice King's origin. "A Prince Named Bert" and the alt-world episodes. "Bad Little Boy" reimagines fables.
Season 6 — "Wake Up"
The longest season. The Lich returns. "The Cooler" deepens PB and Marceline's complicated romance. Lemongrab gets the devastating "You Made Me."
- "You Made Me" — Lemongrab 1's origin and the birth of Lemongrab 2. One of the most quoted episodes online.
Season 7 — "Bonnie & Neddy"
Marceline and Bubblegum's past is explored. Finn's dad Martin appears. "Varmints" gives us the Gumbald revelation, setting up the finale arc.
Season 8 — "Two Swords"
Stakes rise as Gumbald, the Lich, and Orgalorg weave together. "Water Park Prank" and "Bad Jubies" balance the heaviness. Finn turns 17.
Season 9 — "Orb"
The shortest regular season. "Slime Central," "The First Investigation," and the awkward teen episode "The Diary." The show starts winding toward its ending.
Season 10 — "The Wild Hunt"
The final season. "Marceline the Vampire Queen" and "Come Along With Me" — a 4-part, 44-minute finale that aired as the series closer.
- "Come Along With Me" — The series finale. A 44-minute epic. GOLB arrives. Finn sails away. The show ends on a song.
Distant Lands (2020–2021)
Four specials on HBO Max that continued the story in a serialized, hour-long format. Some of the most acclaimed Adventure Time content ever made.
- BMO — A solo adventure with everyone's favorite little robot.
- Obsidian — Marceline and Bubblegum finally address the past, with guest star Ming-Na Wen.
- Together Again — Jake and Finn reunite in the afterlife.
- Wizard City — Peppermint Butler's dark past as a wizard.
Fionna & Cake (2023)
The gender-swapped spinoff from Ice King's fan-fic gets its own series. Fionna, Cake, and Simon Petrikov (now de-crowned) traverse a multiverse. Created by Adam Muto.
The World of Ooo
Set roughly 1,000 years after the "Mushroom War" — a nuclear apocalypse that wiped out most of humanity. What remains is a strange, vibrant, post-post-apocalyptic land of kingdoms, magic, and a few surviving humans.
Sugar, Science & Sovereignty
The political and emotional heart of Ooo. Ruled by Princess Bubblegum from the Candy Castle. Home to the Banana Guard, Peppermint Butler, the Earl of Lemongrab, and most of the show's recurring cast. (See the honorary page for its full history.)
Penguins & Pajamas
Once the home of the Ice King, this frozen realm is full of penguins, ice constructs, and Gunter (who is actually the dormant cosmic horror Orgalorg). After the finale, it's ruled by the reformed Ice King, who has been returned to his true self as Simon Petrikov.
Volcanoes & Villains
Ruled by Flame Princess, who starts as Finn's flame-love interest and becomes one of Ooo's most powerful rulers. Volcanic, full of lava constructs, and home to the Flame King's castle.
Jellyfish & Storms
High above Ooo. The kingdom of the sky people and the source of the candy-colored rain. The Earl of Lemongrab's castle floats here in the clouds in some eras.
Home Sweet Tree Fort
Finn and Jake's home base. A treehouse full of video games, swords, and the occasional elephant. BMO lives here. So does a recurring mouse.
Mystic & Mysterious
Magic, dryads, gnomes, and the cosmic entities. Prismo lives here, in his timeless dream-time space, just outside of Ooo. The Farmland, the Candy People's village, and many sub-kingdoms are tucked among the trees.
Marceline's Realm
The dimension of demons, ruled by Hunson Abadeer (Marceline's dad). Dark, jazzy, full of banjos and broken hearts. A place where the soul can be retrieved — for a price.
Where the Regulars Live
The everyday Candy People — Mr. Cupcake, Marceline's dad Mr. Cream Puff, Cinnamon Bun, and many more — live outside the castle walls. They're the heart (and the comic relief) of the kingdom.
Afterlife & Beyond
The cosmic space where souls go. The Catalyst Comet appears here every thousand years, and it's where GOLB, the cosmic evil, waits. Jake ends up here for years before "Together Again."
Legacy & Cultural Impact
What started as a short, weird, post-apocalyptic cartoon about a boy and his dog became one of the defining animated series of its generation. Here's why it stuck.
🏆 Critical Acclaim
Multiple Primetime Emmy nominations, including a win for "A Christmas Without Santa" and "A Single Part Is Not a Problem" (Outstanding Short-Format Animated Program). Frequently ranked among the greatest animated shows of all time by Rolling Stone, IGN, and Paste Magazine.
📚 The Storytelling Curve
Few shows in animation history have grown the way Adventure Time did. Early seasons are gag-driven, almost surrealist. By the back half, it's doing serialized, emotionally devastating arcs about trauma, codependency, and what it means to grow up. The rewatchability is in watching the bones of that growth.
🎶 Music as a Character
The show produced an enormous catalog of original songs — "I'm Just Your Problem," "Everything Stays," "Bacon Pancakes," "The Lich Song," "Goin' Up and Down" — most written by Rebecca Sugar, Marceline's real-life voice actress Olivia Olson, and series composer Tim Kiefer.
💎 Spawned an Era
Adventure Time launched the careers of Rebecca Sugar (Steven Universe), Patrick McHale (Over the Garden Wall), Adam Muto (who became showrunner and later created Fionna & Cake), and Pendleton Ward himself. The show's creative DNA is in nearly every successful Cartoon Network and Max original since.
🛍️ The Merch Empire
From the iconic BMO vinyl figure to thousands of licensed products, Adventure Time merch saturated toy aisles, Hot Topic, and Comic-Con booths for a decade. It also made Mondo a serious collectible music label thanks to its soundtrack releases.
❤️ The Fandom
Adventure Time fans grew up with the show. Many are now the same age as the showrunners were when they made it. The show deals with aging — Finn literally grows up over the series — and that parallel keeps the fandom emotionally invested in a way few cartoons achieve.
📺 The Return
Distant Lands (2020–2021) brought the gang back in hour-long specials, with "Obsidian" delivering the long-awaited Marceline/Bubblegum resolution. Fionna & Cake (2023) continues the universe with Simon Petrikov navigating a fractured multiverse. The world of Ooo is not done.
📖 The Comics & Books
Bongo Comics and later BOOM! Studios published long-running Adventure Time comic series that expanded the lore, including the "Marceline and the Scream Queens" miniseries. There's also "Adventure Time: The Art of Ooo," a definitive behind-the-scenes art book.
His Lordship, the Earl of Lemongrab
An Honorary Page • The History of Sir Lemongrab & The Candy Kingdom
A Sour Beginning
Sir Lemongrab was first introduced in Season 1's "Power Animal" (2010) as a faint, reedy voice shouting commands at the Candy People. Viewers didn't see his face for several more episodes. When they finally did, in "You Made Me" (Season 6, 2014), the joke snapped into focus: a tiny, lemony, dignity-obsessed royal made from a piece of candy by Princess Bubblegum herself.
A Timeline of Sourness
CREATION
Princess Bubblegum creates Lemongrab from a piece of her own candy essence, hoping to bring peace to the eastern Candy People. He quickly becomes loud, demanding, and entirely unmanageable — a perfect commentary on unintended consequences.
THE EARLDOM
In "You Made Me" (S6 E7), Bubblegum formally appoints him the Earl of the Candy Kingdom and builds him his own castle. She expects him to be grateful. He is, in his own way, deeply — uncomfortably — grateful.
THE SECOND
When Lemongrab 1 falls ill, Bubblegum creates a second Lemongrab — a "peasant" — from a lemon to keep him company. They bicker, abuse the royal we, and eventually harmonize into a chaotic royal couple. They adopt a small, terrified Candy Person child as a prince.
THE UNACCEPTABLE ERA
"UNACCEPTABLE!" becomes the Earl's signature cry, often accompanied by "MY SUBJECTS!" He runs his kingdom with a mix of cruelty and weird tenderness. The Candy People both fear and tolerate him.
THE GUM WAR
During the events of Season 9–10, Lemongrab is the first to recognize Gumbald's treachery. He loses his earldom in the resulting conflict and ends up simply "untitled," which — to his quiet horror — is a relief.
THE QUIET ENDING
In the final episodes, the Earl moves into the Candy Castle as a kind of permanent royal guest. He is, finally, a member of the family. He and Lemongrab 2 retire from screaming. Mostly.
Why Lemongrab Endures
Lemongrab is a strange, often uncomfortable character. He's loud, petty, sometimes cruel — and also achingly lonely, desperate for love, and trapped in a role he never asked for. He is, in many ways, the show's most human character despite being made of citrus. The fandom has rallied around his existential screaming, his tragedy, and his unexpected tenderness, especially toward his adopted son.
A Kingdom Born from Sugar
The Candy Kingdom sits in the center of the Land of Ooo and is built, quite literally, out of candy. The castle is a confectioner's dream. The walls are pastel. The Banana Guard wear banana skins. The currency is presumably gumdrops. It is, on the surface, a children's fantasy — and underneath that, the most politically complicated place in the show.
A History of the Candy Kingdom
THE MUSHROOM WAR (Year 0)
A global nuclear conflict — the Mushroom War — wipes out most of humanity. In the ashes, strange new life emerges. Princess Bubblegum is among the first sentient beings created from candy during this period, along with the rest of the Candy People.
BUBBLEGUM'S ASCENT
Princess Bubblegum — Bonnie — establishes the Candy Kingdom as a sovereign monarchy. She is its creator, scientist, and sole ruler. By the time of the show, she is roughly 18 years old (candy people age slowly), but functionally thousands of years experienced.
THE GUM WAR
A long-ago conflict between Bubblegum and a fellow candy being, Uncle Gumbald, ended with Gumbald's exile to the dead lands. Peace held for a thousand years. The details were redacted from the kingdom's history books — by Bubblegum herself.
THE EARLDOM CREATED
Lemongrab is created and given dominion over the eastern Candy People. The Banana Guard is established as the royal military. Peppermint Butler becomes the royal advisor.
THE CANDY ZOMBIES
The Candy Kingdom endures a zombie outbreak (Season 3's "Slumber Party Panic" and beyond), several near-destructions by the Lich, a flame war with the Fire Kingdom, and the constant low-grade threat of Gumbald's return.
GUMBALD RETURNS
In Seasons 7–10, the redacted history comes back to bite. Gumbald, his niece Aunt Lolly, and nephew Chicle return from the dead lands, claim territory, and start the Great Gum War. The conflict nearly destroys everything Bubblegum built.
THE SECOND GUM WAR & GOLB
Gumbald ultimately sacrifices himself to stop the cosmic entity GOLB, and the war ends. The kingdom is battered but standing. Bubblegum finally confronts the truth about her own history.
COME ALONG WITH ME
In the series finale, the Candy Kingdom endures one final assault — GOLB itself. It's defeated through music, friendship, and one very good song. The kingdom survives. The era of princesses and earls, of swords and spells, gently gives way to something quieter.
Daily Life in the Kingdom
Beyond the politics, the Candy Kingdom is also a place of daily absurdities. The Candy People throw parades for the slightest victories. They stage funerals for the recently stepped-on. The Banana Guard are surprisingly competent when not being comic relief. The castle has a fully functional science lab, an inter-dimensional prison, and at least one royal plumber. It's a kingdom that contains multitudes — sweetness, paranoia, science, and a quietly tragic royal lineage.
In solemn recognition of His Lordship's service to the Candy Kingdom, and with all due respect to his royal dignity, we hereby dedicate this page to the most sour, the loudest, and the most misunderstood Earl in all of Ooo.
