Smoke Ball

Smoke Ball is an item in Super Smash Bros. Brawl. However, it doesn't do any damage. Once thrown, it will emit colorful smoke into the air, which can be very distracting to the players. It is also hard to see what moves are being used, and it is difficult to see what's going on. Players can pick up the item, and take it, or throw it somewhere else.

Trophy Information from Super Smash Bros. Brawl
''An item that activates when tossed and fills the area with clouds of obscuring smoke. The smoke slowly changes color over time, from white to yellow, orange, red, purple, and finally blue before restarting the cycle. The smoke hangs around quite a while before dispersing. You can pick up an active smoke ball and hurl it again. Be careful not to lose track of yourself, though.''

Trivia

 * There is an item in the Pokémon series called Smoke Ball. This item works similarly to the Smoke Ball from Super Smash Bros. Brawl, however the Smoke Ball in Super Smash Bros. Brawl is not from the Pokémon series, as it has the Smash Bros. series's logo on the official site instead of a Poké Ball.
