Forget about zapping car thiefs with electro shock. I want on of these.

Nice story. Making someone jump into an alligator pond is ..somewhat.. less easy done than zapping him. Or did you want to "install" a live one in your vehicle? I think it will take exception.

Yeah, not as convenient as trunk monkey

I was thinking along the lines of Miami Vice and Elvis, IIRC the gator's name, on Crocket's boat.

The thief breaks into the vehicle, while the thief works on the ignition, a detection spell detects the unauthorized occupant locks the doors and triggers a transformation spell changing the mouse in its flimsy cage under the dash into a gator. Or transform some nice sized gators into mice and put them in a flimsy (for gators - not for mice) cage under the dash, and when the detection spell goes off it drops the transformation spell.

Hmmm... One word comes to mind... "Karma"

Hmm. I think my mage has a few points of karma left...
