Secret StarHow To Obtain
Secret Slide 1Once you have obtained several stars, you can unlock the door in the top right of the castle. In here there are three stained glass pictures of Princess Toadstool. Jump into the right side window to enter the secret slide. To grab the star, all you need to do is get to the bottom in one piece
Secret Slide 2Re-enter the secret slide. This time you have to get to the bottom in 20 seconds or less. If you're struggling then consider these tips:is: Ride down the start of the track and as the wall to your left starts to dissapear, veer to the left and jump off. Control your landing onto a later part of the course and press Z as you are about to land so you don't fall off. This should cut some time off.
