Stock Ball

A Stock Ball is an item in Super Smash Bros. Brawl, found only in Adventure Mode: The Subspace Emissary. A Stock Ball is surrounded by a bright purple and yellow glowing aura, and has a silhouette-like image in the center. A Stock Ball, as its name would suggest, gives the player an extra stock upon being picked up. A Stock Ball usually appears after defeating a group of several enemies.
