Finding secret car pieces:
The first piece in the Sand Castle level is at the
starting line. Go under the flag and turn around.
You will see a large beach ball. Enter the opening
between the ball, the sand castle, and the starting
line. The second piece in the level is immediately
after the large red shovel jump. Go over it and turn
around. Enter the snorkel. The third piece immediately
follows the shovel jump. You will go between two small
sand towers. You will see some starfish on the left wall.
Turn around to face the two towers again. The one on the
left has the final star.
The stars on the Office level are a lot easier to find.
The first is immediately after the first fork in the road.
Follow the right path and go straight. Enter the small door
or opening in between the books and the computer. The second
piece is immediately after the Hotwheels bridge. Go slow
through the left hand turn immediately after that bridge.
Enter another small opening in the books on the left.
The third piece immediately follows the second fork in
the road. Take the right path at the fork and go slowly
forward. Enter the hole in the yellow pencil box on your left.
The Bedroom level is the hardest place to find the stars.
Immediately after the starting line is a green snake on the
left. Go into its mouth to find the first star.
The second is on the train tracks. The train will enter a
green bridge on the left -- go into it. The third is the
hardest to find. Immediately after the dartboard jumps with
the checkered floor you will go through a broken tennis
racket. Go through it slowly. Go slowly over the jump and
turn around. Enter the a hole on the left.
