Species (The Monsters of Coal Hill School)

A horde of aliens were brought to a replica of Coal Hill School on another planet by a creature who intended for them to learn about English and French from Clara Oswald and Jeff Delobel in the hopes that it would proceed to them invading Earth. The Twelfth Doctor came to the planet looking for Clara. He told the creatures stories of an adventurer who defeated would-be conquerors. The Time Lord asked them to guess of whom he spoke, and with the realisation that it was the Doctor the creatures abandoned their scheme. (COMIC: The Monsters of Coal Hill School)

Most of the creatures were seemingly identical, all a burgundy-brown colour with striking orange eyes and long tongues, however some of the creatures had fur consisting of either brown, blue or green in colour.
