Spewpa is small, cocoon-like Pokémon mostly hidden by fluffy white fur with square particles of red, black, and pale yellow in and around the fur. Poking out of the top of its fur is its large, round head. The head is light gray in the back with a darker gray face. There is a beige dot over each eye and the face is bisected by a thin, black line that ends in a beige triangle at the top of the head. Its eyes are also beige with square, black pupils. In order to defend itself, Spewpa will bristle its fur to threaten predators or spray powder.
Two Spewpa were used by the Lumiose Press editor-in-chief in PS562, to stop X from protecting Alexa. With their Rage Powder, the Spewpa prevented X's Marisso and Salamè from listening to X's commands. Eventually, both were defeated, but X's Pokémon were left exhausted afterward.
Spewpa appears as a Poké Ball summon. It uses Stun Spore to temporarily stun any nearby opponents that attack it, but doesn't move otherwise.
