Adipose

The Adipose were a race of vaguely humanoid blobs of fat.

Biology
Young Adipose were short, marshmallow-shaped beings, composed entirely of fat. They had two eyes and a mouth on their face, two arms with webbed hands and two stumpy legs. However, this may not be representative of the entire species. To grow, Adipose consumed more fat. They could convert other material into fat and consume that, but this would not be good for them.

Life Cycle


The original life cycle of the Adipose is unknown, but once they became a space-faring race they would seed other planets with Adipose seed (despite being in direct contravention to the Shadow Proclamation) which would develop into young Adipose inside another lifeform and escape during the night - although in cases of emergency they could all be released at once, resulting in the death of the lifeform.

Technology
Adipose technology included the pills used on Earth to germinate young Adipose and Nursery Ships equipped with levitation beams. (DW: Partners in Crime)

History
At some point in their history, the Adipose became a space-faring race. After the Adiposian First Family lost their nursery planet, they hired one of a species known as wet nurses, this particular wet nurse began seeding Earth with Adipose seed. On Earth they set up Adipose Industries and disguised the Adipose seeds in the form of weight-loss pills, gaining over a million customers quickly. Matron Cofelia is the proper name of the wet nurse hired by the First Adiposian Family. Matron Cofelia, whose pseudonym is Miss Foster, created Adipose Industries. When the Doctor and Donna Noble discover the alien secret behind the supposed diet pills Matron Cofelia orders the immediate birthing of all Adipose. The Adipose Nursery Ship collected the babies then ordered the death of Miss Foster for her crimes, as breeding on a Level 5 planet is a illegal under the Shadow Proclamation.
