My mom REALLY doesn't like creepy-crawlies of any description, so it was extra traumatizing.

Crayfish can travel quite a long ways out of water. We caught some in a river near our house, brought them home, and put them in a tank. About half of them escaped overnight. My mom found the one while she was getting ready for work the next morning when it crawled out from under her dresser--apparently mobile dust bunnies with claws are quite terrifying.

We found most of the rest of them, but one of them just disappeared. We think maybe our dog ate it?
