"You can talk?", you say as you stare down at the now anthro squirrel. "Yes", he says, "I guess it comes with the opposable thumbs." This is better than you expected. You could now go on with your test.
You look down at the squirrel once more and say, "I want to ask you a few questions, if you don't mind." The squirrel said, "OK". "Do still have your animalistic abilities like climbing trees", you ask. Without one word, the squirrel goes up a tree, leaps from branch to branch, and comes back to where you are. He simply says, "Yes".
Your next question is, "Would you mind living like a human with clothing and a house?" The squirrel says, "Not really. But if it means giving up my animal side, then no. I love my tail and my fur."
You had all the info you need now. You still have one more question for him, "Do you want to change back now?" The squirrel answers, "Yes, please. I don't think my nest would accept me like this." You know what to do. "Lago", you say to the rabbit who is watching all this, "I wish this squirrel was back in its original form." Lago replies, "As you wish".
The squirrel is soon back on four legs and goes back up the tree he came from. As you see him go out of sight, Lago says "I assume there was a point to this whole thing?" You say, "Yes".
