You Start the game on level one, which appears to consist solely of two islands
in the water. However, if you jet ski, fly, or ride an inner tube to the lower
Left part of level 1, you will find another island with a hole in it. Fall Down
the hole to level 0, where you can be healed (in the hot tub) and receive an
extra life (by drinking lemonade). When you leave level 0, you will return
to the highest level you have visited.
You can get 2 or 3 presents from Santa if you sneak up on him while
he's rummaging through his bag, and stand still when he looks up. Do
this until you touch him and he drops some presents when he leaves.
