Wall Buddy (Character)

Wall Buddy is the main antagonist (though it's not really clear if he's evil or just a malfunctioning computer) from the episode Wall Buddy.

Appearance
Wall Buddy is voice-activated consists of a seemingly endless amount of walls, that can stretch and shift in all directions and even create windows, originally to separate and/or rearrange rooms. His CPU is a black box with a number field and a red, round cameralense on it. Underneath the lense is his reset-button.

When Mordecai and Rigby gave him too many commandos at the same time, Wall Buddy overloads and starts to malfunction, which causes him to create a giant maze of walls in the entire park and the house. They manage to stop him by hitting the reset-button under the red lense on his CPU.

Trivia

 * His CPU looks almost identical to HAL 9000, the computer from Stanley Kubrick's 2001: A Space Odyssey.
 * The way he creates the wallmaze with highspeed in the end of the episode resembles the way the lightcycles from the movie Tron create walls behind them while driving.
