Vampire

The mansion had two floors. There were five vampires living in the mansion: Blue, Red, Second, Yellow and Green. Vampires typically fed on human blood. They could survive on animal blood, but it didn't quench their thirst completely. Of course they could eat regular food... Now they were sitting at a table on the second floor and eating human food, but they were drinking animal blood in glasses that they had caught and squeezed out. Blue, Red, Second, Yellow and Green were suddenly distracted by the sound of rustling and someone opening the door on the first floor, it was you. It was dark all around and you couldn't see anything. It all started when you decided to take a walk in the forest.
