JJ, Polly Pockets weren't around when we were kids but boy were they big when my daughter was little. She got them for Christmas, birthdays,in Easter baskets, etc. They are these precious little cases that open and become playgrounds, nurseries, stores, etc. They have teeny tiny dolls and pets that you move around within the case. I'm sure I vaccumed a few of the dolls right along with the Legos.
