I've gone and gotten myself some work kritturs. Said critters are 3 hermit crabs. I have not named them yet, two of them were extremely active on the way home, the other is actually quite the hermit and didn't even move until it had been sitting in the terrarium (the crabitat if you will) for over an hour.
I set out some fresh food from Bond (grapes and spinach) so we'll see how much they eat.
The biggest problem with said crabs? They're nocturnal so I probably won't get to watch them move around much.
