World 3: Ghost House

Coin 1

From the get-go, there's a secret area just left of the entrance where you'll find a coin.

Coin 2

When you reach these series of ropes in the second room, you'll find the second coin in a hidden alcove along the left wall.

Coin 3

The final Star Coin is located inside the level's alternate exit. You'll find the a secret door inside the room with the rope running along the ceiling. Once on the rope, follow it so you're just above the left-most position of the first moving platform (that is, where it's positioned when it's moved all the way left). Now wait for it to move away and drop off the rope--don't worry! You'll hand in a hidden area below, containing a door. Once through, you'll find yourself in shaft with a floor that begins to lower slowly, then will drop all of a sudden. After that first sudden drop, look for the coin in a secret alcove along the right wall.

Alternate Route This Ghost House contains a secret exit that leads to a cannon on the world map, which will blast you to World 6. Here's how to find it: When you reach the room with the rope running along the ceiling, follow the rope so you're just above the left-most position of the first moving platform (that is, where it's positioned when it's moved all the way left). Now wait for it to move away and drop off the rope--don't worry! You'll hand in a hidden area below, containing a door. Now just follow the rest of the level to the secret flag pole.
