Billy Bevel is the best friend and next-door neighbor of Olie Polie in Rolie Polie Olie. His debut was in episode 3 of Season 1, in the second segment "Monster Movie Night." Originally, he and his family are from Planet Cubey, but they moved into the round planet Polieville. However, there was room for a square house. Billy's parents are Baxter and Bonita, and he has an infant brother named Binky (who debuts in the segment "Baby Binky"), and an orange cat named Dicey (who debuts in the segment "Dicey Situation"). Everything about Billy is square, except for his eyes and the base under his torso, and he doesn't seem to wear anything, though he has a green diamond on his tummy. He was voiced by Joshua Tucci and Kristopher Clarke.
