A - From the start of the map you can head to your straight and look up and to your left at a high hill, you should spot it easily, though you can't get it from your position. Just climb up a bit and you should be able to get it where you grab the Energy Gun, I used the Energy Gun to get it anyways.

O - This is easy to find, just get to the top and drop off the ledge so you anchor on and you can see it under the platform.

R - As soon as you go in the cave go to your right, you will see a little cave like thing here, go all the way in, turn around and look up. Should be quite visible on the wall.

R - This is going to be up where the stalagmites are on the ceiling. To find it keep heading up the ramp and when you get to the spot where 4 of the Tentacles pop up and there is a Trilid nest and some rocks here, do a 180 and look at the stalagmites behind you, it's in there.

U - This is easy to get, when you get near the top, there will be a ledge across from you where a wasp is lying down. Knock the wasp off and you can spot it at the same spot the wasp was at.

A - Just above the exit into the room before the boss. It will be to your left in a small crevice.
