SMS Glitch: Ride Yoshi underwater

Danchastu tested, Yoshi approved. It works but may take a few tries. Have fun.

In Delfino Plaza, go to the statue in front of you (the one where all the nozzle attachments are. Now look to the left and up. On the building to the left you should see a set of windows, the one on the left is closed and the one to its direct right is open. Now get Yoshi and spin jump BETWEEN these two windows. Try to spin jump (and hover) all the way to the top of the building. Right before the very top press toward the wall, you should glitch right through the wall and you will land in a weird blue room. DONT stop moving here the second you land fully, do another spin jump and you should be on the floor of the river. Yes you can use this to go to the hard to reach pipe on the island in the middle of the sea.
Please dont flame, I just want to pass this along, if you dont beleive me fine you dont have to. Please try it for yourself.
I found the blue room by accident, I found the rest out by luck. So have fun and please post here if you can confirm this.
Also dont jump with yoshi once you are in the water or he will die. Just walk with him.
