Ochre Jelly (Basic Lore)

Ochre Jelly (CR 3)
Neutral - Large - Ooze
Ochre Jelly is a vile, magical form of unnatural existence. It's not truly alive, nor is it properly dead. It is a hungry thing that creeps about in an eternal quest for food. When it has grown large enough, it splits into two new jellies, which each continue their mindless ways. Ochre Jelly is, thankfully, one of the least dangerous forms of ooze, although that's rather akin to saying a house fire is less dangerous than a forest fire. Ochre Jelly has no mind, it is simple and direct. It senses warmth and vibration, it moves toward the warmth and vibration and eats whatever it finds until it is large enough to split. If it does not sense warmth and vibration, it oozes about at random, usually moving five feet every five minutes or so. It will slime its way right up walls and across ceilings without trouble, and will enter water without even knowing it's no longer in air. Ochre Jelly can be encountered literally anywhere, and tragic stories have arisen from a jelly that slips into a house at night.
