We all went crazy for these egg sized digital pets that needed your undivided attention. It was like having the responsibility of having a pet without any of the mess. Tamagotchi taught us 90s kids valuable lessons: Everyone needs food, play and some TLC…..and then you die! There was no other doll in the world that was so adorably small as the original Polly Pocket. Each compact came in various shapes and inside were completely different worlds for Polly Pocket to live in.
