Mega Grindarr is an enemy which debuted in Kirby Mass Attack. It is similar to Grindarr, though much larger. In addition, when it falls, it sticks out its tongue. Mega Grindarr appears only once in each of the games it appears in, and despite its similarity to standard Grindarrs, it doesn't actually end up posing a threat to Kirby, as it is never in a position to crush him. Instead, Mega Grindarr is either used as a stage prop, or Kirby rides on top of it.
