Howie Mandel said that he accidentally created the voice that would be later used to voice Bobby when he was choking on a piece of cake at a birthday party when he was 11.
On February 12, 2007, the character Bobby made a surprise appearance on an episode of Deal or No Deal (2005).
The voice Howie Mandel used for Bobby is the same voice he used for Skeeter on Muppet Babies.
Howie Mandel used the voice of bobby as a blueprint when he was coming up with the voice of gizmo for the gremlins franchise.
The setting of Howie Mandel as a real human in the animated world with Bobby was possibly inspired by Falsches Spiel mit Roger Rabbit (1988) released 2 years prior.
