Who was the other hand for Bart for one scene in Jazzy and the Pussycats?

Question

In Jazzy and the Pussycats, Bart's drumming hand got bitten by an animal Lisa was keeping in the attic. In a later scene, he shows jazz stars he can drum again with someone else's arm. Then the hand held a sign and left. It didn't show who's hand it is. Do you have the answer?

Answer 1

Try observing the hand and then looking at character articles on this wiki to see which character's hand matches the hand in [[Jazzy and the Pussycats]] that you wonder about.
