Rolie Polie Olie (1998)

S1E8 Squaresville / Zowie's Harmonica / Unruly Polie Olie

Olie builds a square-shaped world for him and Billy to explore and play in, while Zowie discovers a harmonica and can’t stop tooting around the house. At first, Olie and Billy love having no rules in their new world—they do whatever they want. But soon they realize that chaos isn’t as fun as it seems, and a little order might be just what they need.
