About this sound
Rigby shouts 'oh no my gumballs' in a fast, high-pitched panic lasting just over a second. The tiny disaster feels wildly out of proportion, which makes the distress funny, frantic and instantly contagious for listeners. The line comes from Regular Show, the animated series about park workers Mordecai and Rigby and their surreal everyday disasters.
