A recall where you are swarmed by puppies- You whistle, and a bunch of puppies come running at you, and once they knock you down, they pile on and your recall completes. I would love for it to have the PC giggling and/or yelling "PUPPIES!".
A recall where it starts to rain, so you pull out an umbrella and do a little dance that ends with you starting a spin, toss the umbrella in the air, and when it comes down you disappear and the recall is complete.
A recall where you throw some birdseed down out of a small bag, and a bunch of birds land and start to eat, then they swirl around you(sort of like the bats) and the recall completes.
A recall where you disappear one layer at a time. You make a quick slashing motion with a magic dagger, and your skin disappears, then your muscles, then your innards, then your bones. It would be hilarious if your eyes were last, and fell on the ground before "popping" away one at a time(with a satisfying little sound), and then recall is complete.
