Monster Menagerie – Olive Slime

Whenever it comes to slime (especially the green stuff) I always think of the cans of the gunk you can get at Walmart. This one predates those and sets me heart racing. I loved this module when I was a kid! Gary Gygax‘s The Lost Caverns of Tsojcanth S4 (9061) was a masterpiece for levels 6-10 in 1982.

The horn of Iggwilv
Pierces the heart –
Look over the shoulder
Before you start.

That rainy afternoon we reached the foothills of the Yatils. Little did we know what was waiting for for us. SLIME!

Olive slime is a type of monstrous plant life similar to green slime, but worse inmost respects. Olive slime grows in subterranean areas and feeds on animal, vegetable, or metallic substances. The vibrations caused by the movement of a passing creature will cause it to release its tendrils and drop on the backs of unsuspecting victims.
Olive slime secretes a numbing poison upon contact with another creature. Victims of the slime must save vs. Poison or fail to notice the attachment of the slime. In humans, the slime usually attaches itself along the spine. Others may see the slime attack the victim; circumstances such as lighting, position, and
distance will affect this. Once attached, the slime spreads over the body of the victim, sending parasitic tendrils to feed on the fluids of the host.

After one turn, the mind of the victim becomes affected by the secretions. Thereafter, the victim’s main goal is the protection and continued growth of the slime. The victim will refuse to take off armor or clothes in front of other people, so that the slime will not be seen. The victim must double the amount of food eaten or lose 10% of his original hit points each day. After 1d6+6 days, the host will begin to change into a vegetable creature. Olive slime gradually replaces skin tissue and flesh, and forms a brain attachment as well. The new creature has no interest in its former friends or life. It exists as a new species, more plant than human. The new creature feeds by photosynthesis, parasitism, or both. Upon death, the creature generates a new patch of olive slime. (See SLIME CREATURE for details of plant-like creatures created by olive slime.)

One turn after attachment, the slime will have so thoroughly infected the victim that a cure disease is needed to stop the metamorphosis, even if the slime is killed by other means.

Olive slime can be killed by acid, cold, fire, or a cure disease spell. It is also affected by all spells that affect plants. Other forms of attack, including spells, have no effect on it. Green slime and olive slime will attack and kill each other.
