Super Mario 64/Tick Tock Clock
- Location: Third floor. After collecting 50 Power Stars, the entrance is in the face of the clock.
- Description: A tall level with swinging pendulums and a long drop.
Tick Tock Clock is the fourteenth course in the game. 50 stars are required to access it. 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: Minute (long) hand at 12 (The :00 mark).
- Slow: Minute hand at 3 (The :15 mark).
- Random: Minute hand at 6 (The :30 mark).
- Fast: Minute hand at 9 (The :45 mark).
 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 into 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 to the cage after the three rotating yellow blocks, 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.)
Alternate: Go the same path you would for star one, time stopped. Before entering the cage, stop on the round piece, the star is directly below. It's tricky, but if you drop down pushing right you can slip on the ledge.
 Star 4: Stomp On The Thwomp
Easiest with time slowed. Go as far up as you can. When you get to Wario's hand, just do a back flip over the mesh wall. You will find that the hand of the clock is in the wrong place, but that's okay. Go to the first block that you stand on (it's yellow). Do a back flip and glide to the yellow treadmill. You will find a Thwomp. Jump onto the Thwomp and jump up 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: Tick Tock Silver Stars (Nintendo DS)
In this Star, you don't really have to do anything. All the Silver Stars do is rain down! If a Silver Star falls down the center hole before you get it, it will loop all the way back to the top. After collecting the Silver Stars, you will need to go to the pole-jumping area. Ride the platforms over to your Star.
 Star 7: 100 Coins
Easiest with time stopped. It's also a bit easier if you get all the red coins, but you don't absolutely need to. 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. However, it requires some talent to reach the top of the clock with the platforms stopped.
Practice your wall jumps. It's the only way to bypass one of the frozen lifts.
