Bone Twister

Bone Twisters, also known as Tweesters, are tornado-like enemies that appear in Super Mario Galaxy. They possess eyes and have debris spinning inside them, such as skulls and bones. Bone Twisters can be helpful at times, being used to traverse obstacles. Touching one also causes them to spin around. If the player then spins using the Wii Remote, the Bone Twister makes Mario or Luigi go flying into the air and spins his arms around very quickly like a helicopter. Two Bone Twisters have spiked debris spinning around them, which damage Mario or Luigi if he makes contact with them. They appear only in the Dusty Dune Galaxy in the missions Blasting through the Sand and Purple Coins in the Desert.

Super Mario Galaxy Trading Card description
''These tornado-like creatures can be menacing or actually helpful on occasion. Mario must watch out for the debris that flies out from their gusty wake and also be careful if he bumps into them, because they'll send him spinning. But if timed correctly, Mario can do a star spin into a Tweester and fly up higher than any jump could take him.''
