Rolie Polie Olie

The show focuses on the Polie Family, who live in a teapot-shaped house in a geometric world (Planet Polie) populated by robot-based characters. The stories revolve around a young robot named Olie learning life lessons and going on wacky adventures (either real or imaginative) while growing up. These often include his little sister Zowie, his inventor father, his hard-working mom, his fun-loving grandfather Pappy, and his dog Spot. Although most of the main cast is composed of circular bots, other characters are featured in other shapes, such as Olie's friend Billy Bevel and his family, who are square-shaped bots from Planet Cubey.

• Zowie Polie – Olie's younger sister, Gizmo's niece, Pappy's granddaughter and Percy and Polina's daughter. She is also very inquisitive (The episode But Why?, for example, has her keep on annoying the family by asking "Why?" about everything imaginable) and loud. She loves Olie and enjoys emulating him, sometimes to Olie's chagrin, too. Her name is actually pronounced like the name "Zoey" instead of like the word "zowie" (which rhymes with Howie).
• Spot – Spot is Olie's faithful dog. As revealed in the episode But Why?, he was given his name because he left a "spot" on the carpet as a puppy.

• Space Boy – A young super-hero and star of Olie's favorite TV show Space Boy. Along with his companion Space Dog, he frequently saves the universe from various threats on his show, and occasionally appears to help out Olie.

She first appeared in the Valentine's Day–themed episode Looove Bug, where she moves into Polieville, and Olie and Billy, who compete with each other for Polly's affections, immediately fell in love (via being bitten by the Love Bug) with her until they bumped into Mr. Polie.
