In "Video Makers," BMO edits the film Finn and Jake make in a way to resolve their dispute over the film's artistic direction, even composing a song for them. BMO refuses to "play such games with Jake because Jake cannot deal with losing.
When Finn asks for advice on Jake's attitude, BMO recommendeds that Finn play to lose. BMO has been seen playing video games in "BMO Noire." BMO has also been seen skateboarding in "Card Wars" and "Time Sandwich." BMO also once had to be picked up from soccer in the episode "In Your Footsteps." BMO likes scrambled eggs, as shown in "Her Parents," and hot chocolate, as shown in "Video Makers" and "Holly Jolly Secrets Part II." In "Five More Short Graybles," BMO is shown to "drink" tea while teaching Football manners.
This potentially causes BMO to act like completely different people, and have its "multiple personalities" communicate with each other.
An interesting note about this is that, in reality, both the Atari 2600 and the Sega Genesis have share an identical input device.
This means that both controllers can be hooked up to the same device without issue.
BMO (an abbreviation for Be More, phonetically spelled "Beemo"), is Finn and Jake's living video game console system, portable electrical outlet, computer, music player, VCR, video player, video editor, roommate, camera, alarm clock, toaster, flashlight, strobelight, skateboarder, soccer player, tape player, chef and friend.
They make their appearance in the title scene of the Theme Song of every episode of Adventure Time, just as Finn and Jake pound their fists together.
BMO claims to not have emotions, but this is perceived to be inaccurate.
