Description: Like the other Miguls in the area, except black. You'll need to kill several of them for a quest. Only one spawns at a time, with a respawn time of about 5 minutes (or so the quest text says). They appear in Sewers 4 and 5. In Sewer 4, the Black Migul is in the small alcove midway through, in the same place you have to go for the Sewage Water. In Sewer 5, the Black Migul is all the way to the right, where the path dead-ends.
Strategy: These guys are virtually identical to a Doughy Migul in every way except coloration. However, due to the long spawn time between them, you might have difficulty finding them. The easiest method is to stay at one of their spawn points and switch between channels until you find a channel with a Black Migul spawned.
