Wacky Worlds Creativity Studio is a children's video game for the Mega Drive/Genesis, released in the mid-1990s. In it, the player has a choice of six different Wacky Worlds in which they can place animated "stickers", creating a two-dimensional diorama, of sorts. Among the Worlds are an underwater scene, a scene inside a house, a jungle, and the Moon. The user is also able to alter the music played in each world by selecting from a bank of different music stickers. [source:wikipedia]
