Mumu

a mysterious creature that dwells within the South Wales area, a formidable force in eating and sleeps 95% of its life. They can munch 15 pounds of grapes in 30 minutes, and drink 45 gallons of petrol in an hour.

facts:

average height of 3.5 cm

weighs approx 95 pounds (fully grown)

average walking distance 8ft per day

bodily fluid approx 99% nuclear matter

reproduces via one of three penises and one vagina, both combatants become pregnated, after 9 human months each gives birth to between 2000-3000 offspring

live in traditionaly mounds of moss

mumu's existance is questionable as sources may be unreliable, although mumu's have been spotted many times in real life taking part in urban scrumping, and their corpses found dissolving in a pool of acidic sunstance.
ants: hey sam look in that pool of acid is it a mumu?
sam: yes it looks like it burnt through its own arse.
