BMO

Beemo (or BMO) is Finn and Jake's video game system. He makes his appearance in the title scene of the Theme Song of every episode of Adventure Time, just before Finn and Jake pound their fists together. He made a cameo appearance in the episode "Evicted!", being played by Marceline while Finn and Jake are going house-hunting. He is also seen in "Business Time" when Finn and Jake are playing Adventure Masters on him. Also, in "Business Time", Finn and Jake are seen playing an Abraham Lincoln game. He is later seen in the episode "My Two Favorite People". In "The Witches Garden", Finn was playing a game while discussing with Jake about how he got his magical powers. Beemo also is seen in "What is Life?" when Jake throws a garbage bag of butter on Finn, and in the episode "Donny" where one of the controls is smashed in half. Beemo claims to not have emotions, but Donny angers him by smashing a controller and throwing it at him. In "Rainy Day Daydream", he shows a bored Finn and Jake a new game, "Conversation Parade". Beemo appears again in "Slow Love" where he acts like a rebellious kid, refusing to turn down his music when Jake tells him. He is then pummeled and battered when Snorlock starts dancing with lady snails while the tree house is on his back, but is apparently unharmed and returns to play music at the end of the episode. In "Power Animal", Beemo distracted Jake with songs. They were later eating lunch together and Jake told him to hold his sandwich. He was later seen fixing the well overhang that lead to the gnome's underground hideout that Jake had destroyed while entering. In Guardians of Sunshine, it is revealed he has a button hidden under his control pad that allows people to be transported in games. However, he does not allow Finn and Jake inside it, claiming it's too dangerous an adventure.
