Column (Wario World)
From the Super Mario Wiki, the Mario encyclopedia
A column is an object from Wario World. Much like statues, these objects can be used as weapons against enemies, as Wario can perform any one of his powerful moves (Piledriver, Wild Swing-Ding, Mega Toss) on it. However, a column breaks after just one attack.
Though they are found in other places, columns are always found inside Battle Rings. Columns also appear in the boss fights with DinoMighty and Brawl Doll; throwing Brawl Doll at one of the columns to break it will give Wario a few coins.
