Super Mario 64/Whomp's Fortress

Star 1 - Chip Off Whomp's Block
Travel to the top of the mountain and defeat the giant Whomp. You must ground pound on the bandage on his back. Just stand just in front of him to make him fall over, then quickly jump on his back and ground pound. After three hits, he with relenquish a star.

Star 2 - To The Top Of The Fortress
Again, travel to the top of the mountain, but this time you'll find a tower. Climb it using the moving blocks, and you'll find the star at the top.

Star 3 - Shoot Into The Blue Wild
To get this star, you must first speak to the pink bob-omb and get him to prepare the cannons for you. Having done that, all you need to do is shoot yourself onto the platform to the left - the one under the flag pole. Aim above the platform aboe the star. Once you get there (it may take a few tries if you're not used to the cannon), climb down the pole and the star's right there.

Star 4 - Red Coins On The Floating Isles
Again, find eight red coins scattered throughout the course.

The Star appears in the field near where you started. If you have enough health, you may be able to survive a well positioned fall to the star. No? Just walk back down the mountain and take it.
 * 1) Start in the shallow pool and long jump up the black incline to reach the first coin.
 * 2) On your way up the mountain, there are three pices of wall that poke out at intervals. A red coin is on top of the middle one.
 * 3) The third coin is above the secnd blue Thwomp. Get on the step above him and jump on his head.
 * 4) Another one is next to the piranha plant just pas the Thwomps.
 * 5) Get the next red coin by walking (slowly!) across the ledge past the piranha plant.
 * 6) Travel on the rotating wooden plank for another red coin.
 * 7) The last two are on floating islands off of the top of the mountain. Wall kick the plank so you can safely walk across.

Star 5 - Fall Onto The Cage Island
First, climb up the tree near the start of the level. Once you do so, an owl will come out and offer you a ride. Jump into his claws and steer him towards the cage that holds the star up there in the sky. Drop yourself in and claim your prize.

Star 6 - Blast Away The Wall
Go to the cannon again, but this time aim to the right. You want to hit the side of the brown wall near the top. If you get this right, it will shatter revealing a star (see screenshot to right). Climb up to the wall, slide down to the star, and you've got it.

Star 7 - Get 100 Coins
Again, getting 100 coins is worth a star.
 * Piranha plants are worth a five coins each
 * So are Whomps, but before you ground pound one, jump on it to earn on coin. You can do this up to five times before killing it for five more
 * Blue Coin switch
 * On the floating islands
 * On the rotating bridge
 * Above wild blue

This is the easiest 100 coin star in the game. Coins are everywhere you look. Attempt this while Star1-6 is selected, so that you can get some higher up coins if you even need them (You shouldn't!)
