As part of its ongoing efforts to promote every single Pokémon out there, The Pokémon Company has shared special content dedicated to Wooloo and Yamper:
Wooloo: Its curly fleece is such an effective cushion that this Pokémon could fall off a cliff and stand right back up at the bottom, unharmed. If its fleece grows too long, Wooloo won’t be able to move. Cloth made with the wool of this Pokémon is surprisingly strong.
Yamper: This Pokémon is very popular as a herding dog in the Galar region. As it runs, it generates electricity from the base of its tail. This gluttonous Pokémon only assists people with their work because it wants treats. As it runs, it crackles with electricity.
