Pokemon Pikachu Kigurumi Adult-Size Costume OnesieOfficial Licensed by Pokemon. Designed by Sazac Japan. Did you ever wonder why Pikachu broke out of his Pok Ball? Its because he loves comfort! We pay tribute to him with a Kigurumi so cozy, youll never want to take it off. Super soft and ultra warm, you can kick back and relax as Ashs right hand man. But please, dont get into any battles. This animal onesie may be cute, but it wont give you the ability to electrocute your enemies.
