Glutonoid

The Glutonoid was a monstrously obese alien found on Phijax IV.

The Glutonoid was a large purple blob with antennae, green eyes, a long prehensile tongue and eight tiny hand-like limbs. It was incapable of independent movement due to its bulk and was dependant on a hover pad for movement. It had limited intelligence and an insatiable hunger for food.

At some point in its history, the Glutonoid was able to get to Phijax IV and start up a fighting organisation. Warriors would fight for his amusement and then be eaten if they lost. When the Tenth Doctor and Rose came to Phijax IV, they were chained together and forced to fight the champion. When they won, the Glutonoid still wanted to eat Rose. The Doctor activated the Glutonoid's hover pad using the its handheld device, sending it hurlting into the air. While distracted, the Doctor fed it a mixture of the TARDIS' food pills, with the combination of blueberry pie, bacon, semolina, cabbage and fizzy lemonade causing it to fatally explode.
