Big Grinder

Big Grinders are larger versions of Grinders that appear in New Super Mario Bros. 2. They act the same as normal Grinders, but are slower, and generally cut down larger platforms. They only appear in, and like normal Grinders, they can only be defeated with an Invincibility Leaf and a Super Star. They tend to come from the ceiling or from underwater and chase the player for a while before retreating.
