Squeaky

Squeaky is a villainous mouse from the series WordGirl. He is most known for the fact that his brain is know fused with the mind of Steven Boxleitner, better known as Dr. Two-Brains.

Speaky is an albino lab mouse, used for testing on the structure of the rodent mind. He has white fur, and pink eyes and skin. Attached to his head via thimble is a strange piece of gadgetry (possibly to transmit rodent thoughts to a computer) that he is never seen without.

Squeaky's mind was merged with Prof. Boxleitner's very early on in the series, in one of the WordGirl shorts. The distracted scientist left the rodent alone for a brief moment to check on his pastrami sandwich, and the vicious lab mouse pressed the button on the dashboard specifucally labeled "Holy Cow!! Don't Press this Button!", merging the mouse's brain with that of the scientist and creating Dr. Two-Brains.

This episode has been the only one so far to feature Squeaky (besides a brief cameo during a flashback in "A Game of Cat and Mouse"), for obvious reasons. However it could be argued that any episode with Dr. Two-Brains is an episode with Squeaky, due to them being basically the same person.
