When a witch, Santa Claus, and the Easter Bunny breaks into a musuem, all pandemonium breaks loose.
First, the witch would steal all of the brooms from the janitor's closet to stock up for her witch army back home. Then, she would steal anything that would make her money and/or lure young children into her and her sisters' house to try to suck the soul out of their victims for themselves (See what I did there?).
The Easter Bunny would be a little more dignified, and only take back what was originally his, The Egg Of Hanabalu. The Egg Of Hanabalu was a priceless heirloom of the Hanabalu family, given to them by the Easter Bunny as a precious gift. It was lost after the fall of their country, Ishmahbavlakya. If the family couldn't have it, neither could the musuem.
Santa Claus neither came for revenge nor for foolery. He meerely came as a ride for the witch and the easter Bunny. After the witch brewed up some dirty laundry of Santa's and told the Easter Bunny about it, it was the only thing Santa could do to keep their mouths shut. He had a few magical elves back home brewing up an amnesia potion to give to them so he never had to come close to spilling his secret ever again. No one would ever know, and he'd never had to cover his tracks again.
