Rat: not even an enemy. They just run around.
Fox: Dodges sometimes, and can attack and move in the same turn. A complete pain in the ass.
I think I can tell what half of the enemies are, but none of the ones on the first floor. In the second zone, we have scorpions, but I don't know what the second is. In the third zone, ghosts and frogs. But what are the other three?
unless you have several jumps/suplexes, a few bolts, and like, twenty spins, you're done for.
