Never done the easter bunny thing but wish we had now.
We do a treasure hunt with different clues that leads them to another. I had do this so that my little DS doesn't get beaten to all the eggs by his big sis. This year I've added moshi monster eggs in the hunt so the questions are going to be about moshlings. At then end of it they're get some new moshi figures instead of chocolate which they're not so bothered about but mummy feels the need to scoff when they get left in the cuboard for months on end un-eaten.
