“Why do boys like to get so mucky?”

Wilson Gets a Wash is the twenty-sixth episode of the first season.


Calley and Dunbar teach the trainees to brake in mud, but after getting dirty, Wilson is scared to go through the Chug Wash and so he escapes. He gets out of being washed by telling Eddie that the Chug Wash is broken, but it isn't. But Brewster and Koko eventually catch Wilson and bring him directly to the Chug Wash. Now Wilson must face his fears, but when he does, all the trainees want to get washed up again!
