Hermit crab Darwin award

This little guy was stuck in a hole in the rock for a week. He got himself free and went right back in. It took me 15 minutes to get him back out and I put a shell in the hole to keep him out. Today, he decided to change into that shell, on the rock. Needless to say, I was a tad worried. He is now climbing the rock in the new bigger shell. Hope he stays out of the holes.
