Grims are a type of very small Hoodlum which appears in Rayman 3.
Grims are the smallest of all Hoodlums. They look much like a tiny Hoodblaster, only with a green cloth and no hat or gun.
As a means of attack, Grims carry a single explosive bottle of plum juice, identical to those used by a Hoodboom. However, not possessing the physical capability to throw it, they simply run into their enemies in a kamikaze-like fashion, which damages the opponent at the cost of the Grims' life.
Grims are used by the Grim Keeper as its only means of attack; when Rayman approaches him, he sends the Grims he keeps underneath his robes to attack.

Trivia
A Grim is featured in the Rayman 3 minigame Racket Jump. In this, he throws the Molotov Cocktails onto the field which the Grim Keepers then play tennis with.
When defeated, the Black Lum inside a Grim is not released like other Hoodlums.
If the player locks onto a Grim and views its information, it gives the information used for a Hoodmonger.
