Crabbers are an enemy in the Super Mario Galaxy franchise. They resemble crabs, but have a big pincer and a small one.
Crabbers always turn their face to Mario to prevent him from reaching their rear end, which is their weak point and must be hit with a star spin to destroy them. Mario can use his Star Spin to stun them and buy himself time to run around them. Upon defeat, Crabbers drop three Star Bits. Crabbers have a turquoise variant that drops a 1-Up Mushroom upon defeat, but is harder to defeat.
