Baby Riki Season 1 Episode 45 Flat

Pandy finds a cardboard square she calls a "cube." Chichi tries to stand on it but gives it back, saying it's too flat. Crashy wants to use it for his tower but also returns it, saying it's too thin. Pandy tries to feed it to make it bigger. The Narrator explains it's just a square. Crashy then realizes it could be a window, and Pandy uses it for his tower.
