Nightmare Creature
From Tardis Wiki, the free Doctor Who reference
Nightmare Creatures were created by the Cynrog from the minds of children. A fisherman named Carl Tucker was killed by a hook-clawed one. The Doctor and Rose Tyler also encountered several varieties such as a tentacled one and a centipede. The Doctor and a few others found them garish-coloured and a bit puzzling. They were nocturnal.(NSA: The Nightmare of Black Island)
