Bubbles is the round orange bird from Rovio's Angry Birds series, known for inflating to a huge size before popping back down, and his idle chirps are the small sounds he makes while waiting on screen in the games. Fans have pulled those short game sounds onto soundboards and meme pages, where the chirp works as a quick, recognisable bit of game audio even for people who have not played recently. Its brevity and cartoon charm keep it useful for short edits, reaction videos, and playful background moments.
