There are secret levels in the Astro Barrier mini game at Club Penguin. To get in to these expert levels play up levels 10 or 30. (Or better yet use the Astro Barrier Level Jump Cheat). After level 30 and before level 10 you cannot access them. Before you start one of these levels just wait at the opening screen for 30 seconds. Keep an eye out for passing ships. When you see a blue ship come by, shoot it. You will now have access to the secret levels.
