Choomahs are very erratic and crazy, and most are incapable of speech, with the exception of Bumble Brutus.
The Choomahs come in all shapes and sizes, and have different features. (e.g. some have teeth while others don't, some have two heads.)Clarence's mysterious yellow formula is the source of the Choomahs (featured below).
According to Norton, Doctor C (Clarence) was instructed by King Larinox to make a formula that would result in the creation of super soldiers; instead it resulted in the creation of an abomination, The Choomahs.
An abomination was created because Doctor C’s formula was sabotaged; we assume that it was Glen, as he was the first to find out that the formula had started agitating and moving vigorously.
The formula transformed Doctor Clarence from a human to a "potadahead", as Leslie would say. This explains why Clarence is able to communicate with the Choomahs, as each have the same origin. Clarence is knowledgeable about Choomahs, for example he knows they can “smell sound waves”.
The Choomahs caused the destruction of Kingdom Cum, not Leslie and Norton.
The Choomahs slaughtered the Kingdom Cumians, causing the planet to implode on itself.
The formula was dropped into a pit on Choomah Island, and many Choomahs arose from it.
The Choomahs were eventually destroyed by Clarence , when he exploded a Sassy Foods portable stove (SasM8) deep within Choomah Island.
The name Choomah sounds very similar to "tumour".
This is potentially related to Jarrad Wright's friend, "Dug", dying from cancer, a disease that causes tumours.
The design of the Choomahs were created by Tom Hollis, who stated he was "drawing Homer Simpson retarded" once, and this ended up being the design chosen for the Choomahs. They are also voiced by Tom Hollis.
There are several known forms of Choomahs.
- Standard - This form is the most commonly seen around Australia and it's surrounding oceans. It usually bellows a loud scream before attacking it's victim.
- Large - This form is uncommon, and is known to knock out humans, jump incredible distances and easily break bones.
- Choomahdactyl - This form consists of wings, and a standard body. This creature has only been seen with two legs, and sharp claws.
- Behemoth- This form is the most rare, being only seen once in the Attack on Brown Town. The Behemoth is a massive mutated form of the Choomah, being several hundred times more larger than a standard human.
- Thunderer - This rare form has only been seen once in the Attack on Brown Town. This form has the capability to shatter the ground and send tearing earthquakes in a direction to strike someone and knock them off their feet.
- Special Form : Brutus - Bumble Brutus is the only known "Brutus" Choomah known to exist. He was seen with wings, a large stinger, and exceptional strength.
- Special Form : Choomahviathan- This Choomah was by far the largest seen on the show, however, its life was short-lived and as a result its abilities are not fully known.
- Special Form : Two-Headed Jumper -This is very rare Choomah only seen once on the show. It has two heads, two arms, and two legs. It has a remarkable jumping height and it was able to jump up and take down a plane.
