Kuumyak is a disgusting ooze appearing to be made up of mud and rotting vegetation, making it extremely difficult to spot in the wet areas of the jungle. It will attack by splashing up toward any living creature that passes within 3 feet of it. The corrosive nature of the ooze causes an immediate 1d8 points of damage, and in addition, the victim must make a saving throw vs. poison or suffer an additional 1d8 points of damage from the ooze's toxins.
Kuumyak is immune to all fire and heat damage, but suffers double damage from cold based attacks.
Any creature who is killed by a Kuumyak, and not burned (or revived somehow) will rise as a Khalmaak in 1d4 days.
Some reclusive folk, human or otherwise, of the jungle will often gather Kuumyak to place around their lairs as makeshift, but effective traps. As noted above, Kananicte flowers are sometimes placed nearby to incapacitate victims, allowing the Kuumyak ooze to easily kill them. This can be a nasty, unusual trap, but take care when placing the monsters, for they can have devastating results against PCs who don't roll well on their saving throws. To avoid a total party kill in such a situation, the DM may devise a scenario where NPCs find the unfortunate PCs and drag them to safety, but such a favor will almost always result in the party being asked or coerced into performing some deed of repayment (which is an excellent opportunity to introduce a new plothook or prod the players back along the path of the adventure if they have strayed).
