Yeah, I'd figured as much. I saw ONE on a video in the japanese part of youtube that was being kept in not enough dirt to burrow. I suppose if captive bred enough they might lose their need to bury themselves, but I'd hate to not stay true to their natural environment. I think I'll stick with my pacmans and just keep watching this video 30 times a day, hahahahaha.

EDIT:

God I love how at the end he/she looks at the camera like, "SO THERE!"
