Spewpa is small, cocoon-like Pokémon mostly hidden by sharp 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 from predators such as Rufflet, Spewpa will bristle its fur or spray a poisonous black powder. Spewpa is a nomadic Pokémon, travelling across fields and mountains while building up energy for it to evolve. However, it generally inhabits the shadows of thickets.
Scatterbug and Spewpa each have 20 forms internally, one for each Vivillon pattern. This determines the form of Vivillon they will eventually evolve into, and is determined when they are first generated; for Eggs, this means the game in which the Egg was created, regardless of parents. Of the 20 Spewpa forms, only 19 are legitimately obtainable, as it has never been possible to obtain a Spewpa that evolves into Poké Ball Pattern Vivillon (this was also true of the Fancy Pattern prior to the release of Pokémon Scarlet and Violet).
The forms of Spewpa are mostly indistinguishable from each other until they evolve. However, in Pokémon Legends: Z-A, Spewpa that will evolve into Sandstorm Pattern Vivillon unlock Protect as a Plus Move at level 10, rather than at level 12 like all other Spewpa forms.
In Generation VI and Generation VII, Spewpa's internal form depends on which geographic location the user specified on the Nintendo 3DS at the time the save file was created that it was generated in. Due to region locking, a Nintendo 3DS system can only pick from a certain subset of geographic locations, depending on which region the system is from. For a comprehensive list, see List of Nintendo 3DS country and region settings.
In Pokémon Scarlet and Violet, all wild Scatterbug and Spewpa will evolve into Fancy Pattern Vivillon by default. Scatterbug and Spewpa caught with a Postcard active will evolve into the pattern of Vivillon corresponding to the Postcard. Hatched Scatterbug will evolve into Fancy Pattern Vivillon, regardless of Postcard effects. If a Scatterbug or Spewpa came from another game like Pokémon GO, it will retain the pattern it was assigned in its original game.
Multiple Spewpa appeared in To Catch a Pokémon Smuggler!, all of which had earlier evolved from Scatterbug, including one of them that Ash and his friends helped out. One of the Spewpa later evolved into a Vivillon while battling with Dolan's Diggersby, and the rest evolved afterwards.
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.

Trophy information
NA: Spewpa, the Scatterdust Pokémon. This Bug-type Pokémon can harden its body to protect against attacks. If attacked in Smash Bros., it'll bristle up and paralyze its opponent with Stun Spore. However, it won't do anything if you don't attack it. Don't mess with it—it won't mess with you.
PAL: Spewpa, the Scatterdust Pokémon. This Bug-type Pokémon can harden its body to protect against attacks. In this game, it might bristle up and paralyse you with Stun Spore. "How ever can I avoid such a terrible fate?", you ask? Just leave it alone. Don't mess with Spewpa, and Spewpa won't mess with you.
Spewpa and its pre-evolved form, Scatterbug, are the only black Bug-type Pokémon.
Origin
Spewpa is likely based on the larval forms of certain members of the Tineidae family, such as the carpet moth and case-bearing clothes moth, which construct snug cases of fibres and hairs that leave their heads exposed. The square powder on Spewpa's body might be based on confetti or screen pixels.
Considering its evolutionary relatives, Spewpa may also represent a generic pupa of a moth or butterfly, particularly silkworm cocoons. The way it uses its hairs to protect itself from predation may be a reference to the urticating hairs of some caterpillars that are incorporated into their cocoons for protection.
