Speaking of the 20,000 Leagues Under the Sea Ride, I noticed an odd looking object while using MSN's Live Search Maps. It is sitting in the back of the Legendary Years main building. This picture here isn't as good as using the "Bird's Eye View", but I couldn't save the picture using it.
This link here might provide a better view

I'm not that familiar with the 20,000 Leagues Under the Sea Ride at MK, but from looking at this picture it appears to look like a submarine of some sort. Maybe someone might have some additional info.
