I need one of these little guys for my next pet

In a video titled What is this bug, an unknown creature writhes around on someone's wall. It's too adorable for words. I hope they sell these things at Petco, because this is just the type of companion I've been looking for. If I get one as a pet, I will probably name it Petunia. The person who posted the video is curious what type of critter this is, so if you have one of these too, you should let them know.
