Licker Notes
These creatures used to be zombies before the T-virus further ravaged their bodies. They were named "Lickers" because of their incredibly long tongues they possessed. Other changes involve the brain expanding to the point of becoming visible and their skin deteriorating and peeling to expose their deformed muscle structure.
This last mutation makes it easiest for them to move around on all fours and allows them to climb on walls and ceilings. Physically, they far outperform zombies and they can hunt their prey by sound, lashing out to attack with their piercing tongues. They can also employ their sharp claws to lead and attack.
