Unira

A Unira is an item in Super Smash Bros. Brawl, coming from the game Clu Clu Land. It is a type of Sea Urchin encountered in the said game, acting as an enemy. In fact, it has been referred to as a Sea Urchin in other English localizations, but is known under its Japanese name in Super Smash Bros. Brawl. In Super Smash Bros. Brawl, the Unira can be picked up and tossed at opposing players. After being thrown, its spikes pop out damaging all except the one who threw it. When players stand close enough to it, it draws them toward itself.

A Unira can change "possession", so to speak, if it is attacked. For example, if a player throws it, the Unira will not harm the player; however, if an opponent attacks the Unira, its properties will change and cause harm to the player while not damaging the opponent.

Unira are also seen in WarioWare: Twisted!, in the microgame Clu Clu Land, and in WarioWare: Smooth Moves, which features another microgame of the same name.
