The dirigible peter (dirigibilus peteracus) is one of the rarest creatures in Fungology, with a population of -1.

The Name

The dirigible peter was so named due to the fact that almost every cubic centimeter of space in their body that is not occupied by organs is filled with sacs that contain compressed helium. Their Latin name is supposed to be 'peteracus dirigibilus', but the Fungologist who discovered them, Sir Odren Thingummy, was having an off day when he named them and the name has stuck due to Fungologian Law, however they are still in the genus Peteracus.


Dirigible peters are very round, as the air pressure inside them is about 24,042 PSI they, however, do not explode due to their incredibly tough skin. They inhale vast quantities of air, then filter out tiny amounts of helium using 3 gill-like organs in their chest, staggered along their aesophagus.


Dirigible peters hunt species such as the edible felix, the inflating thomas, the common felix and the tomatoshroom.


Dirigible peters have no way of letting out the helium that is constantly building up in their bodies, they are destined to die at around the age of 420. They die naturally in 2 ways:

1. Bursting- this is when the air pressure within their bodies becomes to high for even their incredibly tough skin, and they explode. This scatters various bodily organs in a 42 km radius, razes all vegetation in a 12 km radius and utterly annihilates all terrain in a 1.2 km radius. In society dirigible peters, when the reach around the age of death, are taken to a tower of reinforced, enchanted, concrete cubes where they are kept until they burst, badly damaging the cube but avoiding the destruction of inhabited areas.

2. Floatup- this is when the sheer amount of helium in their bodies is so great compared to the rest of their bodies that they are lighter than the air that surrounds them, so they float up into the troposphere where they are either eaten by birds or continue to float away.

Other common causes of death for Dirigible Peters include Blak-Sacreatic Cancer, predation by Troons and Daves, and the sport of Peter-Popping.


The Dirigible peter is believed to have evolved about three million years ago, and shares a common ancestor with the inflating thomas.
