Toodles is a flat floating yellow disk that is shaped like Mickey's head, red and yellow stripes on the right ear, red and yellow spots on the left ear. He wears a blue screen with red, pink and yellow polka dots, blue eyes and thin and red lips.
Toodles is a super computer that is always there to help Mickey and the gang find the answers they need. It is always shown to come when Mickey and / or one or all of his friends call "Oh Toodles!". In seasons 1-2 and most season 3 episodes, he is just a helper with no face and no voice approaching Mickey and his friends when they call him. However, in later episodes, he is portrayed as a good friend to them.
