Grimble (Japanese: グリンブル) is a native creature that lives in Gurhacia Valley. It has a chance of being replaced by its rare form, Tormatible.
Grimbles don't really appear until the second part of the Gurhacia Valley but they aren't necessarily that hard to kill. They either attack head on or they opt to circle around the player and then attack from behind, similar to the Vulkure only that this time, they don't have the advantage of being airborne. However, an under leveled player might have a little bit of a rough time killing them, especially if they appear in packs. Attack them with any weapon and don't let them get behind you.
