Bunny Rom Shell List
The Bunny Rom is a very commonly found pet, often on websites such as Wish or AliExpress, or stores like Five Below. eBay and Mercari are also littered with these, and they're almost always marketed as a real Tamagotchi.
These pets have almost no gameplay, and are nearly (if not entirely) impossible to kill.
They all share the same programming and are all 168-in-1 pets.
I have a bit more info about them in the Hall of Shame.
