Fire Eel

You see a six-foot long, fish-like snake burrowing through the sand with aggressive motions.

Tactics
The favorite mode of a fire eel's attack is to burrow near an intended victim and breathe fire on it upon rising to the surface. Should the victim survive the initial attack, the eel will plunge back into the sand to attack from a different point.

Description
A fire eel is a serpentine creature that burrows through the sand living a solitary life, constantly on the lookout for prey. It can breathe a stream of fire at its victim.
