All that is known is that a nice nap at the local PokéPark sometimes has a duo of the critters holding an egg! Transform into the beloved Pikachu with this headpiece. This is an officially licensed hood that you can pop on your top and strap under your chin to instantly give you a pair of Pikachu ears and his iconic smile.
