Poké Ball
From Mariopedia, a wiki on Mario, Yoshi, Wario, Donkey Kong, Super Smash Bros., and more!
Pokeballs are items in the Super Smash Bros. series that when thrown, a random pokemon will come out of the ball, say its cry, and attack. Very very rarely, the player will encounter a pokemon such as mew or celebii. The pokemon dont do any damge to any body, they just fly off screen. However, after the battle, the player will get a huge score for seeing that pokemon.
