However, if you jet ski, fly, or ride an inner tube to the lower left part of level one, you will find another island with a hole in it.

When you leave level 0, you will return to the highest level you have visited.
* Secret Island on Level 1 * In addition to the island with the hole described above, there is another island on the upper right of the level that has many presents on it.
* Presents From Santa * You can get 2-3 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.
