Remember Foster's Home for Imaginary Friends? This little Flash game throws Bloo, Wilt, and the whole gang into a classic memory card match. Flip over tiles to pair up characters—simple, but weirdly satisfying when you nail a combo. The art's straight from the show, so it feels like you're digging through Mac's toy box.

Fair warning: Coco's cards are way harder to match than they should be. Those stubby wings look too similar upside down. Still, it's a solid time-killer if you miss the old Cartoon Network days.
