Shrieker

Name: Shrieker

Description:
An overgrown toadstool mushroom resembling a pallus, and the most basic form of all mushrooms. Its size can vary, going from being as small as a pinky finger to as big as a fat dick.
Has no tentacles, no eyes, no anything. The only way it interacts with the outside is also the reason for his name, namely the shrieks he uses as a sonar much like bats would... though unlike them, the shrieker can't move around no matter what may happen to it.

Culture:
Shriekers can't move, can't see, can't eat, can't do anything other than live. And that's what they exactly do.
They get nutrients from their roots down in the ground and don't strive for anything, they are just another plant on the bottom of the ecosystem... or would be, if not for their peculiar shrieks.
In fact, shriekers can read the vibration on the ground and whenever it happens... whenever someone or something gets closer, the mushroom being to shrieks loudly till the vibration from the ground and feedback from the shrieks cease to be, which is also the reason this monster has a rating of E despite being unable to attack by itself.
The shrieks may be annoying at most, but they act as a great alarm against intruders which in turn draws unwanted attention against them, a bad move if there are many monsters around.

Habitat:
Usually found in dimly lit places like caves. Could be also planted in dungeons by someone, whereas it's unlikely for a shrieker to survive anywhere in the open.

Breeding Habits:
Being immobile, shriekers can't find mates by themselves, therefore they have to make it so the mate comes herself.
To achieve this goal, those mushrooms make use of their spores.
Shriekers in fact regularly breath out their reproductive spores in the same manner humanoids regularly breathe to survive, and this lead to them permeating the mushroom living area with tendency to accumulate. Not to mention that the older they are, the more spores they let out.
This means that an heavy amount of spores wafts around the paths leading to shriekers, and any female breathing them in would be aroused and seeking for a phallus to relieve themselves with.
The more they breath in the stronger the effect, and if the shrieker is the first dick they find...

Being immobile, how to increase their chance of actually being that first dick? The answer is quite simple. A female affected by the spores wouldn't find the shrieker's shrieks annoying, instead feeling very drawn to them... and that's not even mentioning how, whenever it shrieks, the mushroom also release an heavy cloud of spores from below his cap.
Once the female finds the mushroom and welcomes it within her folds, the shrieker would keep blowing out spores clouds into her pussy till it permeates her insides... which mean the girl would be kept horny enough to keep fucking the fungus till it withers or its shrieks attract pissed males very willing to vent their frustration into the horny girl.
Even if it withers, the girl would be kept aroused by the spores within her womb and seek for males to mate with.

In fact the spores would grow nourished by the proteins within the sperm of whatever would fuck the pollinated girl, and settle on whatever ground said girl squats down to drain the cum out their pussies. Every was of cum leaking out as they walk can potentially lead to a new shrieker, and if the girl wash herself within a water course the spores would flow along and hopefully find a new ground to grow on.

Danger Rating: E
