Obsessive...

I perch like a gargoyle on some high vantage, glowering down at the world

I submerge myself in noisome muck with only my eyes poking above the surface

I wait behind a trap door or breakable wall, then burst out like BLAAARG

I look exactly like a pile of trash, debris, and/or bones until I stand up

I dwell in a deep and narrow hole and bite you when you try to look inside

I snipe you at range from a direction you wouldn't intuitively think to look

I come flying in from outside the camera's draw distance at Mach Fuck

I resemble some harmless environmental feature, forcing you to smash them all

I go invisible under certain conditions; can't go wrong with the classics!

I don't "lurk", as such, I just have a really bullshit spawn trigger
