Blob the Builder (建) and Joan of Arc (ji) want to construct (建) a Go (廴) field in the anthill's bathroom (an4), so they paint the field on the floor using decorator's brushes (聿).
Sherlock Holmes (sh) started a supermarket (市) in the space station's bathroom (Ø4), but all he has for sale right now are berets (亠) and towels (巾). He should have opened it at the beach!
