In the home world (the world you start the game in), go thru the gate w/the electric lock. You'll go to a farm place. Go right, and there will be an entrance there (make sure the entrance is dirt, not grass). Go in. Once there go under the dock (but not underwater). Face so you're tail's facing the ground. Keep pressing A. It will take a few times, and you're under, but walking. You can even use fire in there! To get out, press every button (I'm not sure which one). you may come to a point where Spyro moves foreward w/out you(but you can move him up,down, left and right). If he does, press A and hold it, and Spyro will be as still as a statue!
