The Ood set for Doctor Who return

One of Doctor Who's scariest aliens will be back to wreak more terror in the fourth series of the hit sci-fi show.

The Ood - who are known for their red mouth tentacles and a bald head - will return for a special episode called Planet of the Ood.

Viewers will learn where they come from and discover whether the Doctor and his new companion Donna will befriend the creatures.

The Ood first appeared in an episode called The Impossible Planet last year.

They were recently voted the sixth most scariest Doctor Who villain, after the likes of the Daleks and the Cybermen.

Writer and executive producer Russell T Davies has described the Ood as "the most brilliantly made monster in the world", adding they look like "they're permanently throwing up. It's really disgusting"

The fourth series will appear on TV screens in spring next year.
