Adipose

The Adipose were a race of vaguely humanoid blobs of fat. (DW: Partners in Crime)

Biology
The Adipose were a short, marshmallow-shaped race, composed entirely of fat. They had two eyes and a mouth on their face, two arms with webbed hands and two stumpy legs. However, because only young Adipose have been seen so far, the adult version could be very different. To grow, Adipose consumed more fat. They could convert other material into fat and consume that, but this would not be good for them. (DW: Partners in Crime)

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 loss of their nursery planets, they 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 took control of Adipose Industries and ordered the immediate birthing of all Adipose when the Doctor and Donna Noble intervened. The Adipose Nursery Ship took the babies away then they killed Miss Foster, their accomplice, as breeding on an alien planet is a crime. (DW: Partners in Crime)
