What was the name of the mouse that Dumbo the elephant made friends with in the Disney cartoon?

Dumbo is a 1941 American animated film produced by Walt Disney Productions and released by RKO Radio Pictures. The fourth Disney animated feature film, it is based upon the storyline written by Helen Aberson and illustrated by Harold Pearl for the prototype of a novelty toy ("Roll-a-Book"). The main character is Jumbo Jr., a semi-anthropomorphic elephant who is cruelly nicknamed "Dumbo". He is ridiculed for his big ears, but in fact he is capable of flying by using his ears as wings. Throughout most of the film, his only true friend, aside from his mother, is the mouse, Timothy – a relationship parodying the stereotypical animosity between mice and elephants.

Edward Brophy as Timothy Q. Mouse, an anthropomorphic mouse who becomes the only friend of Dumbo after his mother is locked up and does his best to make Dumbo happy again. He teaches Dumbo how to become the "ninth wonder of the universe", and the only flying elephant in the whole world. He is never mentioned by name in the film, but his signature can be read on the contract in a newspaper photograph at the finale.
