Skimpymoomoo is a member of the black ops elves. Skimpymoomoo is a member of Squishydodo's group, which goes renegade after Santa Claus is driven mad by his anger at Bun-bun. When the elves return to the North Pole to answer a distress signal seemingly from Mrs. Claus, they find it infected by spore aliens. Skimpymoomoo wears a short dress (a "skimpy muumuu") when out of uniform.
