Vilk is an enemy that appears in the Locker portion of the Alcatraz Elementary School. He's a vampire made from a milk carton with a missing poster of Ned on its side. His lair is a diorama of a haunted castle. Vilk's name is a portmanteau of the words "vampire" and "milk".
Vilk is vulnerable when exposed to sunlight. Ned must hit the chandelier on the ceiling to break a hole in the wall. The sunlight will shine on Vilk, rendering him vulnerable to attacks.
When defeated, he will turn into a model of a house back at the Locker.
Bite - Vilk will bite Ned in the neck if he gets too close.
Bodyslam - Will jump up in the air and slam Ned into the ground.
Summon Bats - Cardboard bats will swoop down to trip Ned.
- He is the only boss in the Locker who speaks.
