Red Shell (trophy)

Red Shell belong to Red Koopa Troopa's, which, in the game Super Mario Bros., are a smarter version of Green Shelled ones. They turn back if they walk to an edge of a pit, unlike their counterparts.

As a Trophy

Melee:

''Throw a Red Shell, and it will home in on random characters and send them flying straight up. Red Shells moving around the surface are dangerous to all players, but they may also present attack chances for players with good timing and strategy. Red Shells won't leave the platform they're on once they start moving. ''

As an item

Red shells wander on a platform, and if there is a character on it, shell will ram into him/her, sending the victim flying. Placing them on little platforms and forcing foes there may be useful.
