Pellet

Pellets are items from the Pikmin series that appear in Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS, and Super Smash Bros. Ultimate on the stage Distant Planet. They grow on Pellet Posies, which they can be knocked off of by attacking them, at which point they function like normal throwing items, allowing them to picked up and thrown at opponents to cause some damage. There are three possible colors pellets can have (namely red, blue and yellow), and each has a number on it that determines its size, although these factors make no difference to any damage they may deal. When a pellet is thrown into an Onion that may appear on the stage, the Onion will use up the pellet to release items. In addition to their appearance on the Distant Planet, pellets have a trophy in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U.

In WarioWare: Get It Together!, the microgame Pikmin 2 requires the player to harvest a pellet.
