Spring

The Spring is an item that appears in Donkey Kong Jr., Mario vs. Donkey Kong, Donkey Kong and Super Smash Bros. Brawl. In Brawl, like a few other items (Peanut, Peach, etc.), the Spring does not appear regularly like a typical item, but appears after a certain attack - in this case, Sonic the Hedgehog's Spring Jump. If Sonic does this in mid-air, the spring simply falls to the stage, damaging anyone unlucky enough to have it dropped on them. However, if he performs it on the ground, the spring temporarily sticks where it is, allowing other players to use it. It will disappear after approximately six seconds.

There is also another Spring in the game, which is modeled after the Mario series. Unlike Sonic's Spring, this Spring is a normal item that appears in the game regularly. If jumped on, a player will be launched in the air extra high than with a normal jump. If the Spring is knocked on its side, however, the player will be launched sideways.

In Mario vs. Donkey Kong, the spring appears in many levels, including some boss battles. They are often needed to clear levels. They are placed on the ground or sometimes in mid-air.
