Merrill and company will find a Piloswine!. It will be Level 30.

Piloswine is a walking pigsty. It's absolutely filthy, and seems to have a perpetual cloud of dust and debris around it at all times, regardless of how many times Merrill bathes it. It's quite cheerful and good-natured about it though, and has no problems with said baths. They just don't seem to do any good.
