Grindels are a type of Thwomp that first appeared in Super Mario 64. They appear to be mummified Thwomps with small black eyes and a huge evil grin on their faces. Not only can they attack vertically which is the normal Thwomp fashion but can also attack horizontally by "jumping" back and forth. Grindels appear twice more in the Super Mario series in the Mario Party 2 minigame Lava Tile Isle and in the Super Mario 64 remake, Super Mario 64 DS. Spindles which also appear in Super Mario 64, which is a rolling obstacle, has the same appearance as a Grindle.
