Obstacles

Entrance Portal
Each island comes with an Entrance Portal which cannot be removed from the island.

However, it can be moved around the island like Decorations and Habitats.

Clearing Obstacles

 * Each island has a lot of Category: you can choose to clear to gain more experience.
 * Some people choose to leave some Category: in their parks for aesthetic reasons. However, you cannot move the Category:.
 * Clearing Category: cannot be undone.
 * The starting island has small Category:, but as each island gets added, bigger obstacles, which take longer and are more expensive to clear, are added.

Each Island

 * Please note that you will not be able to completely clear the starting and second islands until several levels after they are unlocked.
