I have been stuck on this stage for the last 2 weeks and I am in desprete need of help. I already beat the first boss and traveled threw the sand gates 3 times. So I come to this part in the game were the prince finally decides to team up with the princess and the both see the Viser or how ever you spell his name she says who is that blah blah blah they try and open the door I figured out how to get the door open but the tricky part is how to get to the door. I know you have to use that Slow Mo. Feature but does anyone know if there is a easier way because you only get 4 sand tanks and that door closes preety fast!!!
