Timothy Q. Mouse is the deuteragonist of the 1941 Disney movie, Dumbo, originally voiced by an uncredited Edward Brophy.
In "Single White Dad", Timothy appears on the roof of the Griffin Home during Peter's hijinks as he attempts to keep Lois and Becky from meeting up. While Peter ponders how to get off the roof after being trapped in the attic, Timothy offers him a magic feather so he can fly to the ground, but it turns out to be a fake. After Peter faceplants on the doorstep, he is told that this was revenge for always putting locks on his garbage cans.
He is voiced by Jay Pharoah.
