"But if I did it on April 1st, you wouldn't have fallen for it!"

Hyperactive prankster. If she's standing in one place grinning, you should be worried. She's usually the punch line counterpart to Jethro's exposition.

[She's anthro by default, but this is the best picture I have atm; I'll draw a better anthro pic later]
