Super Mario 64/Tiny-Huge Island

Location: Upper floor of castle, through a door with a star on it.

Description: A level much like the first one, with one exception. Mario will be either big if he enters on the left side, small if he enters on the right side, and will swich sizes if he goes through a pipe.

Bob-omb Buddy As big mario, go to where the cannon is. Your Buddy is there. (Hint: the cannon is on the other side of the wall from where you start, then across all the water.)

Star 1: Pluck The Pirhana Flower
Enter the course as big Mario, and long jump twice to the left. Jump in to the pipe and kill all of the pirhana flowers as small Mario by attacking them (with the B button)

Star 2: The Tip Top Of The Huge Island
Make your way to the top of the island as small Mario. The star is in a gold ! box. It is easiest to start as big Mario and change to small Mario near the top.

Star 3: Rematch With Koopa The Quick
Koopa the quick is waiting for you near where the cannonballs roll out (as small Mario). Beat him down the mountain for the star.

Star 4: Five Itty Bitty Secrets
Find all 5 secret spots when you are the big Mario. One is where the cannons come out, one by the hole in the beginning, one by the entrance to the red coins (see star 5), one is above the cannon, and one is at the very top.

Star 5: Wiggler's Red Coins
As small Mario, 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.)

Star 6: Make Wiggler Squirm
Go to the top of the mountain as big Mario. Butt slam the ground to make a hole. Go back up as small Mario and enter the hole. Butt slam the worm three times for the star.

Star 7: 100 Coins
When you are small mario, you can butt-slam 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 impossible to collect. Change views around the generator and you will find it.
