The Blood Moon is random event that happens during an entire night. The chance of it triggering is 11.11% if at least one player has over 120 health points on a night with the moon present. When it begins, the message "The Blood Moon is rising..." will appear in the lower left corner. Multiple Blood Moons in a row can occur. During a Blood Moon, the enemy spawn rate increases (even near your home and NPCs), zombies can open doors, small animals such Bunnies, Penguins, and Goldfish will transform into enemies, and the sky, moon, water, and rain will appear red.
