Just to the left of the pillar, the cow is flying on a bat.

EDIT: There are a few more cows. One just to the right of the pillar,just below Yenwood (Its what the giant is most likely on top of) And another in the middle of the previously mentioned cow, the previously mentioned giant, and MrSnowGlobe. There also appears to be one on the other side of the ridge directly below the flying cow. If I knew how html worked I would circle them all. :(

EDIT 2: I think Terra might be in the picture with a broken skin, as the banner the person is wearing resembles Terra.

I will dig deeper.

EDIT: Here's what I discovered.
There are 3 coal ore blocks in view on the mountain to the left. 3 = Illuminati (Already proven many times) So far what we have is that we know illuminati is involved, just like it is in Pokemon. Pokemon, Professor Oak. There are 5 Oak Trees and 8 Spruce Trees. Oak is illuminati, so we need to remember to not count the fake tree that spies on us. Which leaves us with 4 Oak and 8 Spruce. 4 is half of 8, and both types of trees are alive. Half-Life is confirmed, but how do we know its Half-Life 3? Remember the coal ore? 3 Coal ore, Half-Life 3 confirmed.
