Black Eye

This one is found right in the begining of the level Crow's Nest. Right when you spawn go up the stairs and go over to the left wall. Theres a crate type furnace thingy and jump on that. Then jump on the horizontal pipe that you see in front of you. Then jump on the pipe to the left. It's a really big pole, its like a wall on the pole that you jump on. After you jump on that huge pole keep walking forward. They will be a skull at the end of the pipe thingy and its kinda like a circle platform thats at the end and that the skull is on.

Sorry no pic
