Wakiri

A Wakiri is a buzzsaw similar to a Grinder that appears in Super Mario Land 2: 6 Golden Coins. They move along N&B blocks found throughout the final stage of the Mario Zone, shortly before Mario faces the Three Little Pigs. Unlike Grinders, they do not follow tracks in mid-air and are slower, simply moving back and forth. They can be destroyed if Mario runs through them while holding a Star.
