Bubbles is the small orange bird from Rovio's Angry Birds games, known for suddenly puffing up to a much larger size, which makes a cartoon boing a natural match for the character. The boing itself is a classic cartoon bounce sound long used in animation for springs, jumps and elastic movement. As Angry Birds clips and gameplay edits spread on video and soundboard sites, short effects tied to familiar characters were clipped and shared on their own, and this one remains popular for light, game themed comedy.
