Why are there stalactites in the DS submarine demo?

They don’t even look good. Not in comparison to the rest of the demo, which looks amazing. Sort of a cross between In the Hunt and some game with no enemies anywhere. You guys should download the movie.
I hope they turn it into a game. Apparently it was Miyamoto’s favourite demo of the show, and I can see why.
You could have some pretty cool music for it using the sonar sound as a base. It could even up the tempo when you get close to objects or whatever.
So yeah, I’m bored.

Does you gots a the link?
