Observatory Observation Station is a level in the video game World of Goo. It is the fourth and final level of the Epilogue, and the last of the game. A view of the entire island with the telescope can be viewed. As it turns out, there are no Goo Balls left since they're all sucked away by the pipe system. Fortunately, there are several flying Fish in the water which can be attached to the telescope which causes the entire island to be uprooted and leading to the ending. This level is also home to the telescope easter egg.
