Blocky is a mischievous block character from Battle for Dream Island, the animated web series that later continued with Battle for BFDI and The Power of Two. Known for playing pranks on the other contestants, Blocky often breaks into loud, gleeful laughter when a joke lands, which made his laugh a favourite for fans to isolate and reuse. As BFDI clips spread across YouTube and social media, the laugh became a shorthand for chaotic humour in fan edits, reaction videos and memes, especially among viewers who grew up with the series.
