Haunted House Hole: 
To get a hole in one, hit the ball from the tee to the light grave on the
left side of the house. If you do this correctly the ball will come out
the back of the house. This only works on the first shot.

Abominable Snowman Hole:
Putt into the middle tunnel for a hole in one.

Moon Base Hole:
Hit your ball into the metro station when the sign says 3. If you don't
time it correctly, the ball will fall into the construction pit.

Jungle Hole: 
Across from the pyramid with the hole there is a pool of water. Putt your
ball at the bird next to the water. The bird will pick up the ball and drop it
in the cup.
