Super Mario 64/Tiny-Huge Island
- Location: Second floor. Enter the door with a star on it, and there is a room with three paintings of different sizes.
- Description: A level much like the first one, but has two islands: one small, one big.
- Bob-omb Buddy: On the tiny island, go to where the cannon is. Your "giant" Buddy is there. The cannon is on the other side of the wall from where you start, then across all the water.
Tiny-Huge Island is the thirteenth course in Super Mario 64. Mario will be either on the small island if he enters on the left side, on the giant island if he enters on the right side, and the island will switch sizes if he goes through a pipe. The entrance room has three offshoots, one to the small painting (to the tiny island), one to the large painting (to the huge island), and the third one is normal-sized, except that you cannot enter it.
 Star 1: Pluck The Piranha Flower
Enter the course on the small island, and long jump twice to the left. Jump in to the pipe and become "tiny". Kill all of the giant Piranha Plants by attacking them. There are five flowers total, and a simple punch will kill them. However, they breathe fire, so if you get hit, be extra careful not to fall in the water - the giant fish down there can swallow you whole.
 Star 2: The Tip Top Of The Huge Island
Make your way to the top of the huge island. The star is in a gold ! box, just below the apex. It is easiest to start the ascent on the tiny island and go to the huge island near the top.
On the tiny island, make a charge towards the pipe to the left, and drop down onto the ledge behind it. This triggers a purple button that reveals a bridge for a few seconds. Use a backflip to jump onto the cannonball ramp where you can reach the upper pipe.
If you want to complete the level on the huge island, you need to go through the wall, and swim across. Use the windy bridge unto you reach a bridge leading to the cannon ball ramp. Cross it, and hug the wall as you climb the ramp.
There is a Chuckya waiting a few ledges above the big-island pipe. If you aren't careful, he will throw you all the way back down
 Star 3: Rematch with Koopa the Quick
It's easier if you start out on the small island. Climb up the mountain and go through the tunnel by the boulders coming out. Once you've made mario smaller, go farther than where the boulders are coming from and you will see Koopa the Quick. Beat him down the mountain and you will receive a star.
The easiest way to win the race is to use longs jumps throughout the entire race - until you get to the windy bridge. Once you get there, just stay on the ground and run. You should have enough of a lead from your long jumps to win.
 Star 4: Five Itty Bitty Secrets
Find all five secret spots when you are on the tiny island.
- Where the cannon comes out.
- By the hole in the mountainside near the cannons (bridge leads to it).
- Where the rolling balls come out.
- At the very top of the mountain.
- The small hole in the grey wall where you start, from the side by the beach.
The star will appear on the floating island beyond the big/small pipe on the lowest level. Step on the switch and a number of orange boxes will appear which you can walk across to get to the star.
 Star 4: Klepto the Condor (Nintendo DS)
On the tiny island, hit the switch and make some bricks appear. Walk over to an island. Wait for Klepto to fly over, jump up at him, and grab your Star.
 Star 5: Wiggler's Red Coins
On the big island, launch out of the cannon to the tree up above. Walk across the thin long plank and enter the cave. The coins are inside. You need to swing across the roof for some. Alternative: Either get the turtle shell and ride into the cave or do a wall kick after a triple jump.
 Star 6: Make Wiggler Squirm
Go to the top of the mountain on the tiny island. Ground pound the ground to make a hole. Go back up on the giant island and enter the hole. Jump on Wiggler's head three times for the star.
 Star 7: Switch Star On the Island (Nintendo DS)
On the big island, swim over to the cannon. Fire yourself at the tree and walk the wooden plank and make your way into the cavern. Step on the Star Switch and jump your way over to the Star.
 Star 7: 100 Coins
When you are in big island, you can ground pound the Goombas for a blue coin. There are 15 in all. After that, it's a snap. There are 191 coins in all.
 Impossible Coin
There is a coin near the bowling ball generator that is underground and normally impossible to collect. Change views around the generator and you will find it. Walk up to the right side of the ball generator into the corner between it and the mountain and Mario's feet will go slightly into the map just close enough to collect it.
