Illusory Vampire Bat
A bat swoops at Barbara in the cobwebbed Gothic house, startling her into a scream amid the group's arrival. The Doctor examines it closely and labels it a vampire bat, though he notes such creatures do not hail from Central Europe, signaling its unnatural origin as one of the house's illusions. Ian, Vicki, and others react with alarm, heightening the tense atmosphere as the creature flaps away into shadows.
