I definitely had this exact Polly Pocket set as a kid! Back when Polly actually fit in your pocket. And no one had to tell us, "Don't choke on Polly Pocket," because we weren't stupid enough to eat her.
I used to color on the space maker part with Crayola marker. Then I would put Elmer's glue on it and sit it under my desk and wait for it to dry. When I would go to school the next day it would peel right off.
