Fluffy tamagotchi 1998
Original Bandai tamagotchi

“The virtual pet, while simulating the training and rearing of a helpless space creature, is actually training its user. If you don't feed the pet at regular intervals, it dies. The Tamagotchi and its many clones are training children to attend to technology at the expense of their human interactions.”
