BONUS ACTIONS

Split. If the slime mold is Medium or larger and has at least 10 hit points, it splits into two new slime molds. Each new slime mold has hit points equal to half of the original slime mold, rounded down. New slime molds are one size smaller than the original slime mold. Creatures engulfed by the slime mold are no longer engulfed, but they remain stuck to one of the slime molds.
Slime molds coat the walls and floors of caves, dungeons, and other moist, subterranean environments. They come in a variety of colors and textures, including a fuzzy pink, a mucus-like yellow, and a stony gray. A slime mold often hunts by spreading itself over the floor of a passageway and waiting for a creature to walk across it and get stuck. The slime mold then slowly engulfs and digests the creature, leaving behind only magic items.
While a slime mold can split itself up into smaller versions of itself, the resulting molds continue to act in concert with one another, as if sharing a single consciousness.
Oozes are ambulatory, predatory amoeboid creatures that infest caverns and other dark places. A gelatinous cube is an ooze.
