Get your poles out, gents.

The Lurker Below is the second boss you come to in World of Warcraft's Serpentshrine Caverns, although you don't really reach him. Huh? The trick with the Lurker is that he does not start in the raid instance. To summon him you must fish for him in the strange pool.

*Submerge *- Every two minutes the Lurker will submerge and spawn MOBs
in the room. Two Coilfang Ambushers per outer platform in the room and
three Coilfang Guardians on the center platform. The Lurker will stay
submerged for 1 minute in which time you need to down all 9 adds.
