They remind me of bakugan toys that they have for boys. This must have been the girl's version. They have a button on the bottom when pressed it opens the ball shape to form what look like little animals.
granddaughter loves these. McDonalds did give these out but I dont believe they had houses and they were a bit bigger than the store bought ones. Granddaughter has two from McDonalds and she didnt get houses with them. Fanned and watching.
