Hey Sargent, a speaker monster could actually work for a dubstep area.
Especially if they could shoot "super bass sound waves" from their bodies.
Though only for a certain distance, such as the range of an archer.
They should also move slow enough/be small enough to jump over, for those who aren't archers.
oh, and sorry itblobboy, the emo raver e-tards keep breeding, they are IMPOSSIBLE to fully eradicate.
Though the Cthulhu knows i tried!
