Adipose

"The Holy Grail of the modern age. And here it is. You just take one capsule. One capsule, once a day for three weeks, and the fat just walks away"

A revolutionary diet pill, manufactured by Adipose Industries, once swept London. The pill’s slogan, ‘The fat just walks away’, seemed too good to be true. Unfortunately, it was. Small, white, jelly-baby shaped, marshmallow-like creatures, the Adipose, spawned out of the pill-takers’ bodies at night, destroying the hosts in the process.

When the Doctor and Donna Noble each investigated these pills, they discovered that the head of Adipose Industries, Miss Foster, was in fact Matron Cofelia of the Five-Straighten Classabindi Nursery Fleet. An outer-space ‘Supernanny’, as Donna puts it.

Miss Foster has been hired by the Adiposian First Family after Adipose 3 lost its nursery planet. Her illegal plan was to use London’s overweight population to hatch these new Adipose babies. When the Adiposian First Family arrived in a spaceship, they beamed the young Adipose aboard but dropped Miss Foster to her death for she was no longer needed.

The Doctor refused to take action against the Adipose, explaining to Donna that they’re just children and can’t help where they came from.
