I had a digimon and a tamagotchi. The digimon was fun to train and evolve and bring it to recess at school. I would find someone else with a digimon, hook them up to initiate battle, and then run across the playground and watch the fight.
I remember our neighbors had stolen one of my siblings' tamagotchis at some point. When we tried to get it back, the kid had a Reese's or something, and he goes "I ate your tamagotchi!" and showed us the Reese's in his mouth. I believed it so hard that as I remembered that story just now, I still felt a tiny twang that he really ate the tamagotchi.
