Super Mario 64/Tick Tock Clock

Location: Upper floor of castle, in the face of the clock.

Description: A tall level with swinging pendulums and a long drop.

Stopping Time
It is possible to alter the speed at which time flows in this level, making some stars easier or harder to get. To change the speed you need to enter when the clock is at different times.
 * Stopped: Big hand at 12.
 * Slow: Big hand at 3.
 * Fast: Big hand at 9.
 * Reverse:Big hand at 6.

Star 1: Roll Into The Cage
Easiest with time stopped. Proceed up the clock. After a little ways, you will see a star in a cage. ride the rotating platform in to the cage, and get the star.

Star 2: The Pit And The Pendulums
Easiest with time stopped. Go a little farther than the first star, and jump past the pendulums to the star.

Star 3: Get A Hand
Easiest with time fast. Go up farther than the second star to where the rotating hand is. Stand on it and let it swing you around to where the star is. Another strategy is to go up to the cage like in the first star, then fall down to the platform below (it's possible to complete the star with the time stopped if you do it this way.)

Star 4: Stomp On The Thwomp
Easiest with time slow. Go as far up as you can. Ride the second rotating hand to where the thwomp is. Backflip on to the top of the thwomp and ride it to the star.

Star 5: Timed Jumps On The Moving Bars
Easiest with time slow. Above star 3, you will see three beams moving in and out of the wall. climb them to the star.

Star 6: Stop Time For Red Coins
Easiest with time stopped. Get all 8 red coins. They are on the rotating platforms to the right of the start.

Star 7: 100 Coins
Easiest with time slow. Forget about the red coins. Be sure to get the blue coins in front of star 2. All the rest of the coins are in yellow ! boxes, and just sitting around.
