Red Faction Easter Egg - Cactus?

At the end of the first part of the game, just before you exit the mine. You arrived to a elevator. If ou look behind it you see a little tunnel. Go in there. There should be a little cave with water, plants, bats and all those sterotypical cave stuff.

Well if you look at the celling at the other side of the cave you will see an object coming out of the ceiling.

Now do a hole in the wall to get out of the water. Bring out the console (press /) and type in: heehoo. Now you should fly.

Now go see what it is from closer.
