Chapi Chapo is a 1974 French stop-motion animation series that was also part of the offerings of the Nickelodeon series Pinwheel. The eponymous protagonists were two human-shaped children that wore hats; one blue, the other red. The two children existed in a magical space filled with numerous blocks. When the children touched a block, it could be changed into an object, or its geometry would change to fit their particular need. Interestingly, the children never existed on one spatial plane; they often switched between planes to manipulate shapes.The children weren't the only inhabitants of the space; some creatures recurred in the 60 episodes including a bunny, a small bird, and a cow.
