Frooms? What are those?

Furry Mushrooms aka Frooms are a furry open species that emphasises clean design and pawsitive emotions.

Main characteristics:

  • Strictly Safe For Work, no erotic material allowed;
  • Open species - you can make your own as long as you follow the guidelines;
  • Simple to design;
  • Really cute!


Frooms are mushrooms that are at the same time furries. They have characteristics of both mushrooms and animals.


The singular form is froom. Plural is frooms.

The subpecies of a froom is dictated by the mushroom. Currently the only known/supported is the agaricus.

A type is dictated by the animal that’s mixed with the mushroom, ex. fox or cat.

Froomin' (trailing single quote required) is the act of hanging upside down by the tail or by attaching oneself to a flat surface. This is how many agarici relax.

A froomsona is a froom fursona.


Explicitly supporetd

The supported types are predominantly land animals, such as, but not limited to:

  • Foxes
  • Cats
  • Dogs
  • Wolves
  • Rabbits
  • Hyenas
  • Coyotes
  • etc.

Explicitly unsupported

  • Aquatic animals
  • Avians
  • Fandom specific constructs (primagens, protogens, dutch angel dragons, sergals, wickerbeasts etc.);

Status unknown

  • Cryptids (ex. wendigo)



The agaricus consists of a Bulb seated on a Leg. In front it has it’s eyes. On the back, exactly 180 degrees opposite, there’s the tail. It’s attached right where the leg connects to the bulb.

The leg has really short fur and has variations of shapes. The bulb is a round mass of spongy tissue covered with fluff and receptors. Its porous witch is how the agaricus breaths and smells. Taste is done by rubbing against the object.

The leg has a leg print on the bottom. This is the equivalent of a paw print. Agarici walk by jumping and eat usually by feeding off the ground by rooting themselves temporarily.

Rules of design

Those guidelines are here to help you make a more clear design. The suggested ones can be overruled but only if you have a valid reason. Limits foster creativity.

  • It can have only one leg
  • It has no hands, paws or feet
  • It has no mouth or nose
  • It does NOT speak human and anthro languages12
  • The tail is used as a limb and can shape-shift3
  • Does not combine with other mushroom subspecies
  • You can use at max two animal types4


Furry agaricus usually live in colonies ranging from a dozen to a couple of dozens in size. Every colony has a leader. Since agarici are rather devious and enjoy various frolics, the leader always has a lot of work. If the leader dies, gets sick or disappears the colony automatically selects a new one. The exact method is unknown, but reportedly it requires a lot of buzzing noises.

They enjoy jumping inside tree tops. This is in fact one of the places were they play and relax. Thanks to their elastic tails they can jump like on springs.

The agaricus are genderfull, which means they can have names (like Caesar).

Although they mostly live in forests, some agarici have been known to migrate to towns and other settlements.


The furry agaricus reproduces in a sexless manner: via owo-spores. They land in various places and if the ground is safe and fertile, a fresh froom will start to grow. It initially has no fur and is much smaller. It develops as explained here.

Their means of defense are their tails but also intimidation through sudden, temporary expansion. The agaricus may suddenly get bigger for a short while to make itself look more dangerous. As a last resort, it may use toxic gas it produces. Fumes attack the nervous system and cause distorted vision, disruption of spacial awareness, general disorientation and fainting.

The agaricus are sensitive to alcohol, which burns them. For an unknown reason they’re also terrified of vinegar.


A froom uses its leg as a way to not only walk, but also feed itself and remove waste. It does it by rooting itself back into the ground, for as long as needed. This can last for an hour or multiple, depending how much material has to be exchanged.

While rooting in or out, the froom has to be awake, but can go to sleep afterwards. It’s common for frooms to root themselves and go to sleep. They can then exchange chemicals while asleep.

Final information

In case a new version of the guidelines gets published and has substantial changes, you don’t have to forcefully update.
You are however highly encouraged to follow the latest guidelines whenever updating your froomsona, creating a new ref-sheet etc.




yyyy-mm-dd Initial version

  1. An agaricus can learn to listen and communicate back by body language and sometimes even in writing. That however is subject to many spelling errors since the froom learns phonetically. ↩︎

  2. The native langage of frooms is known as froomian. ↩︎

  3. Shape-shifting is of the limited kind. The tail may look like an item but it’s still flesh. Which is why a froom won’t shape its tail into a hammer; instead it’ll fetch a real hammer to hit something. ↩︎

  4. Initially Caesar was meant to be a fox-cat hybrid that had an out of place raccoon tail, but eventually became a fox. ↩︎
