Vanish Cap Under the Moat - 8 Red Coins

This mission is unique to the N64.
If we go through the wood door to the right of the door to the Hazy Maze Cave in the basement, we will find a flooded tunnel. After swimming to the other side, we find a sign saying "It is decreed that one shall pound the pillars." There are two pillars nearby sticking out from the water. We pound them both once, hear a chime, and the water drains. We can now go through the door to the outside. Once we go through the door, we find the moat mostly drained. We walk towards the waterfall and find a hole in the ground. We go into the hole and into another area.
We get a message when we land: "Welcome to the Vanish Cap Switch Course! All of the blue blocks you find will become solid once you step on the Cap Switch. You'll disappear when you put on the Vanish Cap, so you'll be able to elude enemies and walk through many things. Try it out!" We will! When we land, Mario is grainy and fuzzy, which means, we can pass through enemies like they weren't there. The first 4 Red Coins are down the slide in front of us. The Red Coins are on ledges, so we want to slide slowly to get them and jump to other ledges. We must start on the left side of the slide (when facing it) and slide for the first Red Coin. We move about 1/3 to the right for the second. The third and fourth are in the center and on the right side of the slide. There are also 3 1-ups on the slide. Once we reach the bottom of the slide, we dodge flaming orbs and run around the corner. Coins 5-7 are over elevators that flip at the top. The last one was difficult to negotiate as it is going in the opposite direction of the others. I fell off here several times. If you do fall off, you will exit from the waterfall without losing a life. Around this time, the Vanish Cap may be running out. After the last elevator, the Vanish Cap Switch is nearby. The last Red Coin is on a platform nearby and the Star is in a cage with only an opening at the bottom. We can't get to it normally, so we step on the Vanish Cap Switch. We get a message: "You've just stepped on the Vanish Cap Switch. The Vanish Cap makes Mario disappear. Now Vanish Caps will pop from all of the blue blocks you find! Would you like top Save? Yes/No"
We hit the blue block nearby for a translucent cap. We turn grainy before Mario actually puts the cap on his head. we walk through the cage for the Star.
