Tamagotchis were one of the most popular toys of the 1990s with a whopping 76 million sold globally.
Tamagotchis are virtual pets, which hatch from an egg, and the owner then cares for it by playing with it and feeding it and - lets be honest - falling in love with it a little bit.
If they weren't cared for enough - they died.
It was pretty hectic.
Now Japanese toy giant Bandai has re-released original edition Tamagotchis.
At the moment, they are for sale on Amazon Japan for around $18.
Bargain!
