Honestly there was a time people was obsessed with these things just as much as the other tiger hand held games, while wasn't much of a game compared to the ones we play on tv at the time, it was what some people had.
Never heard of that one, but I had a Tamagotchi and some other thing, my mom also had a Tamagotchi. They were all gifts.
Those things were annoying as hell and they always died after a few weeks no matter how hard I tried to keep them alive. But I still had fun with them.
I had a Tamagotchi, was a little over the figured age on them but was curious in the 90s. They currently are reissuing them as they were 20 years ago or will be shortly this year. Seems today it would make more sense as a phone toy but with backpack clips being hot lately it would have that angle to work from too.
