The Repugnant Appendage is a treasure in Pikmin 2; it is really a dirty pink shoe with a velcro strap and a teddy bear on it. It is found on the last sublevel (8) of Frontier Cavern and is in the possession of an Empress Bulblax that constantly gives birth to offspring known as Bulborb Larvae. When retrieved, the Rush Boots component of the Exploration Kit is unlocked. This special footware allows Captains to run faster, at the same speed as flowered White Pikmin. The Rush Boots also renders the blowing attack of Puffy and Withering Blowhogs ineffective against captains.
