The Wal-Mart where I'm at carries Panfish Worms, Trout Worms, and Red Wigglers - aren't they all pretty much the same creature?

I just get Nightcrawlers. I know what they are, and the snakes gobble them up.

Well, not so much lately - for some reason, Little Dude and Scarlett have both stopped eating regularly. Neither of them seems ready for a shed, either.
