Grocery store plant, what is it?

Alright botanist of Reddit, here's one for you. I found this fun creature at my local grocery store. It was unlabeled except for a list of possibilities, all of which proved to be wrong. For now, I plan to treat it like a euphorbia, hot, dry and basically ignored. Eventually, I will move it into the well draining soil mix I use for me euphorbias.

For your amusement here is the list of incorrect possibilities:

Bear paw succulent
Golden critter tail cactus
White bunny ears cactus
Possum tail cactus
Fish bone orchid cactus
Shark tooth orchid cactus
