Repugnant Appendage

The Repugnant Appendage is a treasure in Pikmin 2 that is actually a pink baby shoe. It is found on the 8th sublevel of the Frontier Cavern where it is held by an Empress Bulblax. When retrieved, the Rush Boots component of the Exploration Kit is unlocked. It is the 189th treasure on the List of Pikmin 2 treasures.

Captain Olimar's Journal
"This aromatic object secretes a tangy odor that could knock out a bulblax! I'm with the ship on this one... I don't want to touch it, either! But I must! For the sake of the company and my family... I must summon the strength to carry on!"

Sales Pitch
"Is this the remains of some giant creature? Its color is striking, but its stench is horrific. Could it be dangerous? The true essence of things in the natural world is often very disguised."
