Species (Run, Doctor, Run)
From Tardis Wiki, the free Doctor Who reference
A humanoid species resided on a gaseous ball. They had heavy builds, bald heads, small eyes, pink skin, four-fingered hands and two-toed feet. They wore togas which were either blue or orange.
Members of this species were watching Fariah Jazbloom's art when it was interrupted by the recently-arrived Eleventh Doctor. Angered by this, they began chasing him through their city. Although the Doctor initially found it difficult deal with their world's shifting gravity, he successfully eluded them and offered to make it the same as any other world. He departed after they turned down his offer. (COMIC: Run, Doctor, Run)
