Sticky. When the slime is attacked with a melee weapon, the weapon may become stuck inside of the slime's body. Any creature making a melee attack against the slime must succeed a DC 10 Strength saving throw to ensure its weapon does not become stuck. If a creature using an unarmed attack fails its saving throw, it becomes grappled.

Objects inside the slime can be seen.

A creature within 5 feet of the slime can take an action to pull an object out of the slime. Doing so requires a successful DC 10 Strength check.

On a failed save, the creature takes 2 (1d4) acid damage and is engulfed. The engulfed creature can’t breathe, is restrained, and takes 4 (2d4) acid damage at the start of each of aabluu’s turns. when Aabluu moves, the engulfed creature does not move with him.
