The turtle is a minor character in Oobi.
The turtle is Oobi's favorite pet. In the "Playdate!" episode, Oobi invites Kako over for a playdate, but cannot think about anything other than the turtle. He plays a turtle game, draws the turtle, and sings a song about the turtle.
The turtle is mostly brown. It has a dark brown shell and four red-brown feet. The turtle's eyes are green with black pupils.
