Ryll Ryll 83ec7a698f Adds pulling rabbits from top-hats (#56773) 
This PR makes it so using a wand on a top-hat makes a rabbit appear in
your hand! Fun! There's a 10% chance that instead of a cute bun you get
angry bees though, but a true performer will soldier on anyway. You can
now also scoop up rabbits in your hands, and scooping animals only
requires one free hand to do so instead of all your hands being free.
