Professor Vanderbird-- er, Vanderbil was working very late in the lab one evening, experimenting on bird chemistry. Somehow, as tired as the poor gerbil was, he failed to read the labels when he grabbed the beaker of hawk serum that was sitting next to his Red Bull and guzzled it down. Long story short, he wound up getting wings... and then some. XD

Vanderbil: "Got... sudden urge... to fly south for the winter! Think I'll make that antidote after my trip to Coco Beach." *squawk*
