Another interesting thing I found in that area with Lump (the smart ogre) is that I could not move the boulder just outside, behind the ogres. No matter where I try to place it there is never a successful placement solution. There might be cool stuff under there, you know?
Throw it first (still reveals nothing mind you) then move it AFTER you've thrown it. The other interesting thing about that boulder is that if you look it seems designed to roll down the hill and likely destroy the bridge to the goblin village though I could find no way to start this interaction.
