On Monday, Cartoon Network is throwing itself a very special birthday party, celebrating two decades of animated shenanigans. To mark this milestone, the network commissioned a two-minute music video featuring almost 100 characters from all corners of the Cartoon Network dominion. EW is excited to provide you with a nostalgia-inducing, head-tripping first look at that music video. (Say, it’s the Powerpuff Girls! Wow, it’s Rosie the Robot! Dear gosh, that’s Samurai Jack!) The video is a collaboration between London-based design shop ILOVEDUST and record label Mad Decent. Watch below, and beware: The video may incite seat-dancing.
