Wormhead

   The Wormhead is a dog-like monster in Silent Hill. Its body resembles an average large dog, though its head is completely covered with worms.

Wormheads are essentially upgraded versions of the Groaners. Due to Silent Hill's corruptible force, the Groaner transforms into a more grotesque and powerful creature. Its head is completely covered in what seems to be a mass of worms (hence the name) and it has gained more mass than its Fog World counterpart
