It's time for a "feel bad" level. And by that, I mean a level where you actually try not to harm a single object or enemy of any type. (One good ex.: Wigglers, the Mario farmers) You'll be running away from either a stressed Wiggler having a bad day or the owner of the farm based on hitting 0 or 1+ Wigglers. I haven't seen any morality-based courses for Wiggler yet, so this may be the first one.
