The Shed Shell is a Hold Item introduced in Generation IV. The Shed Shell allows its holder to be substituted with another Pokémon, even if the opponent is using the Abilities Arena Trap, Magnet Pull or Shadow Tag, or if either of the following moves are in effect:
- Route 228
- National Park: Finish the Bug Catching Contest in 4th Place
For each of the Wild Pokémon listed, a Shed Shell will be held by that Pokémon on 5% of the encounters.
- NOTE: Beautifly and Dustox are exclusive to Pokémon White.
