Super Mario 64 on N64 - Level 13: Tiny-Huge Island - Coins and overview
Level Stars

Overview

This world has 2 entrances. In the castle's large room dedicated to it, there is an immense painting on the right and a small one on the left of the entrance. The small one takes you to the "tiny world" (the enemies are small compared to you) and the big painting takes you to the "huge world" (everything is big except you).
The Koopa shell on the beach of the "huge world" can take you to the top of the level in very little time. You have to jump a lot and it's quite dangerous. Don't forget that by pressing Z, you get off the shell.

1. There is a big purple button to the right of the pipe opposite the start of the "tiny world" that makes a wooden path appear. This bridge leads to a platform where star 4 appears.
2. A teleporter is hidden on this isolated platform (in place of the coin). It will take you back near the pipe.
3. The pink Bob-omb that activates the cannon is on the right of the beach in the "tiny world". The cannon hole is in the same place but in the "huge world".

The 8 Red Coins

The 8 red coins are all in the same cave. To get there, either take the cannon and aim as in picture 1 to grab the tree, or go there with the Koopa shell. To the left of the tree, follow the small wooden bridge that leads to the cave.

Jump from platform to platform to get the first 5 red coins. To reach the sixth, you will need to do a double jump.

For the seventh, also do a double jump and watch out for the flames. For the last one, first go to the corner where the star's shadow is, then use the left wall to reach the top of the platform. Come back down and take the star.

Bonus Star: 100+ Coins

There are nearly 200 coins in this world (192), so you won't have any trouble getting this star. Killing the Goombas with a ground pound gives you a blue coin (5 yellow coins) instead of just one if you kill them any other way. Running around the post near the entrance will make 5 coins come out. There is a blue coin block in the red coin cave, but you should get 100 coins without needing to go into that cave.
