Capsule

Capsule is a small container item in Super Smash Flash 2 that was first introduced in Super Smash Bros. for Nintendo 64. Despite being a staple item in the  series, it is absent from the original Super Smash Flash.

Overview
The Capsule is a simple item that requires a single attack or get thrown, to release the single item found inside. Throwing the capsule at any opponents, delivers 9% damage, though there is a 1-in-8 chance that the Capsule will explode instead, dealing 23% damage and great knockback.

Trivia

 * An oversight by developers allows the Capsule to release another Capsule and even a Party Ball, something that is not possible the Super Smash Bros. games.
