Smoke Ball

The Smoke Ball is an item from the Super Smash Bros. which appears in every installment starting with Super Smash Bros. Brawl. Although it does not do much damage, it emits 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 makes it difficult to see what's going on. Players can pick up the item, and take it, or throw it somewhere else. It can also be thrown onto players, in a similar fashion to a Gooey Bomb.

Super Smash Bros. for Nintendo 3DS / Wii U
In Super Smash Bros. for Wii U, the Smoke Ball is exclusively obtained in Trophy Rush.
