Q: How do I get into Hammond's office?
A: (Provided by Zandor 10/9/1999) At the top of the stairs in Hammond's house is an Astronomy Map. It says Big Dipper, and shows 8 stars, the seven in the dipper and the North Star. The North Star is outlined. If you are standing just in front of this map, and look to your right, through the window, you'll see 8 small stones at the backyard, placed just like the 8 stars in the map. The North Star stone in the backyard hides the white key to Hammond's office.

Q: How do I make a basket?
A: (Provided by Zandor 10/9/1999) How to score points at the baseball court, without ever missing a shot. Place yourself at the head of the "free throwing area", not in the circle, but in the straight line that is parallel to the basket. Now move the mouse to center the basket in the middle of the screen. Then, lift your arm without moving the point of view and place the lower contour of the ball aligned with the upper part of the basket plank. Now throw, you'll never miss it.
