I have an evil dog. A very evil dog. If she could make a wish, the first would would be for an infinite number of baby bunnies to eat because the day she found the nest of baby bunnies and ate them all was the best day of her life and her second wish would be for an infinite number of other things to kill and then play with after she's killed them.
The other one would wish for me to scratch his belly until the end of time, so I'm not giving him any wishes.
To be fair, who hasn't set down the half squirrel they were gnawing on and forgotten about it? Maybe the half squirrel and half rabbit were supposed to go together and make an even more fun animal to maim and kill play with. Cute little Dogtor Frankenstein.
Unfortunately, they were both the back end of the creature, so unless you want to attach the butt of a squirrel to the butt of a rabbit and hope it springs to life, I think that wouldn't work.
