Name ideas for new hermit crabs?

Today, I misted my hermit crabs and to my surprise the Ecuadorian one I have, Crabby, chirped at me, so I let him down to wander in the big tub to dry off. My little ones don't get much exercise by wandering in the tub, so I am going to invest in a couple of minature sized hamster exercise balls, so that they can wander around the apartment or house and get more activity in.

So, I am presented with a new dilema for these kids, I need to come up with new names for the two new kids on the block. They are both Purple Pinchers and I haven't gotten to see much of their personalities, mostly because I have had them for only a few days. Any ideas, if so, leave me a comment.
