Sunky.mpg is a YouTube animation parodying Sonic the Hedgehog, built around Sunky, a cheerful but distorted version of the character who collects rings and sings while everything around him feels slightly off. The video became a cult favourite in the Sonic fan community and inspired fan art, edits and remixes, with Sunky's laugh becoming one of its most recognisable moments. Creators still use it as shorthand for cute but cursed humour, especially in memes and videos that play on nostalgia for early Sonic games.
