I got one for Christmas when I was 4. I remember my siblings and I sitting on Santa’s lap at the mall and we all asked for “Gigi pets” I think that’s what they were. I got a 101 Dalmatians and my brother got a Star Wars one. I don’t remember which one my sister got. Of course being 4 at the time I had no frigging idea how the thing worked. So yeah it was just a thing with buttons for me too. My sister tried taking care of all 3 of them but she would have to wake up in the middle of the night to feed them or something. Very soon after Christmas all 3 died.
