"Hmmmm, sure but if I lose you change Keith back and just leave us alone. Oh, and I guess my shirt is a person too." you say.
The feline smiles widely, "Sure, I am Tom by the way" he says with a suspicious tone.
You drive out to a large empty field with no one for miles, you both exit the car and you notice that as you were driving Tom had put on Keith. "You are wearing my friend, I will wear yours" he said upon noticing your stare.
"Well, for my idea we are going to have to switch", you say
Tom raises an eyebrow, "Oh? What is your idea" he asks curiously while taking off Keith
"Just switch and I will tell you" you say while trying to come up with something.
After you switch, you point the keys at the field producing a large race track, then you point at Keith. A flash of white light hits and a race horse is produced. "Oh, we are racing horses? I have never done that before!" he complains. You fire at his shorts producing another horse, "Neither have I, figured it would be safer than gambling as no one can cheat" you reply. You have watched some horse racing before and you had a decent idea, in theory, of how to ride, but this is the best you could think of in a pinch.
Both horses begin to make sounds of objection, but they do not freak out, it seems they could understand what was happening from their previous states.
"Come on Keith, just help me win and we can get tons of money!" you say. Keith let's out the closest thing to a sigh a horse can make and walks over the track.
