The 'Wheatley Crab' is a surreal meme featuring Wheatley, the neurotic AI core from Portal 2, performing a peculiar crab-like dance. The animation was originally created in Source Filmmaker (SFM) by YouTuber Komegatze as a motion test, set to the tune of 'Mr. Blue Sky' by Electric Light Orchestra. It gained viral status due to its awkward yet charming movement, often used as a 'bait-and-switch' meme similar to 'Get Stick Bugged' or 'Rickrolling.' Fans of the Valve franchise quickly embraced the absurdity, turning the glitchy-looking dance into a symbol of internet randomness and niche gaming humor.
