Star 3 - Get A Hand - Tick-Tock Clock

Start by looking left at the swinging pendulum. Jump across the gap onto the other side when the pendulum swings out of the way to avoid being pushed off.

Climb up the three steps and get onto the treadmill.

Walk to the end of the treadmill closest to the giant yellow rotating block.

Watch the rotating block and jump onto its top as soon as it rotates.

Quickly jump onto the small platform to the right.

You will encounter another pendulum; jump across the pit in front of you.

Follow the brown/white striped platform to the left until it ends.

You will reach three giant rotating blocks next to each other that rotate simultaneously. Jump onto the top of them as soon as they rotate.

Quickly climb to the highest of these three blocks, then jump onto another brown/white striped platform. Be careful, or the platforms will rotate while you are on them, causing you to fall.

Walk past a bar sticking out of the wall that attempts to push you off.

Jump up onto the large tan colored platform.

Walk to the middle of this tan platform and hit the '!' box for 3 additional coins.

Wait at the spot where the '!' box was. Avoid the nearby ball that shoots fire at you.

Wait for a giant minute hand to approach. Jump on it when it comes toward you.

When the minute hand completes a 180-degree rotation, you will see a small alcove in the wall. A Spark (if the spark shocks you, it's no big deal) is guarding this alcove.

Jump into the alcove and grab the star.
