Oh you missed the best one yet!
On paintforestv1, go to the lake in the middle. On the right side of the lake against the cliff is a green light ... walk into it as if the wall's not there. You'll warp to the top of the cliffs, stop moving or you may fall off the top! Look around, you'll be on the tip of a tree. Find the branches and walk down to the ground. There may be a hog there, which makes things faster. Move along the cliffs to the LEFT until you get to the waterfall and the stream across the path.
NOTE: It is a LONG way. Don't doubt yourself and give up!
Once in the stream, you should find a hidden room. Take the halls through the first set of doors, and then you'll see a room with a sloping ramp and anotherset of doors. Walk to the top edge of th ramp (not near the door and turn around so your back is to thebottom of the ramp. Back up until ... well ... you will know when, then turn around.
PLEASE don't post anything here ruining the surprise, so no details about what you see!
