Narwhal Worm

The Narwhal Worm is a creature from Amphibia and a beast that guarded Barrel's Warhammer.

Appearance
The creature is an enormous serpentine worm with one large horn on its head similar to that of a narwhal's tusk, hence its name. Its body easily blends into its swampy environment, having several rock-like stumps and moss on its back which is covered by a shell. The creature has yellow glowing eyes and a mouth full of sharp teeth. There is also a portion of its head which releases clouds of smoke into the air.
