These have the lowest HP of any enemy in the game. This is true normally, of course, but it's relevant here as we actually /don't/ need Peril strats for them, despite having them. I think that's neat.

This might be E or F Tier if they didn't unflip immediately, but since they do, you have to have a little bit of thought to take these out. Decent.

This fight was really awesome.
This is my first successful attempt. I didn't have a concrete strategy for how to beat them, and after a couple of attempts, I stumbled into having Peril. I wanted to make this more consistent, though, so I tried some more to create a better strategy. There's two attempts following this one that use Peril Goombella (faster, but less consistent) and Peril Koops (slower, but more consistent).
