Pitfall

A Pitfall is an item from the Animal Crossing franchise, in which it is named Pitfall Seed. A Pitfall is a white ball with a red exclamation mark on it. In the Super Smash Bros. series, Pitfalls are an item in Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS / Wii U, and Super Smash Bros. Ultimate.

Pitfalls are used in a similar manner as they are in the Animal Crossing games; once a pitfall is thrown on the ground, it will be buried and become completely invisible, with no change in the terrain. If a player walks over the spot in which the pitfall is hidden, a pit will open up under them and they will fall in, immobilizing them and leaving them open to attack.

Pitfalls can also be set in suspended platforms. In this case, if a player walks over the spot where the Pitfall is hidden, they will fall through the platform. However, they will not be buried if the main platform is below them. If a Pitfall is thrown at an opponent while they are in the air, the Pitfall will send them straight down.

Pitfalls do not affect the fighter who planted them. Pitfalls also have no effect on Giga Bowser, who is resistant to flinching, and Wario-Man, who is invincible.

Trivia

 * The Pitfall resembles a Surprise Ball from the Yoshi franchise, although the colors are reversed.
 * If Wario hits a buried Pitfall while driving his Wario Bike, he is sent off flying, instantly KOing him.
 * If someone is buried by the Pitfall on a thin platform, half their body will be seen under it.
