Spongy is a yellow sponge contestant in Battle for Dream Island, the animated object competition series created by Michael and Cary Huang that began on YouTube in 2010 and later continued through Battle for BFDI and The Power of Two. His panicked scream has become a recognisable reaction sound among fans, who rip short clips for edits, memes, and soundboards. It endures because the voice is distinctive, cartoonish, and easy to drop into any moment of sudden failure or surprise.
