Astro Knights Island was the 9th island in Poptropica, and was opened in June, 2009. It is by far the hardest of the islands to complete, using complex puzzles and movements in an outer space setting. For example, the game uses coordinates to label the locations of various planets in the poptropica solar system. (Poptropica is actually a separate planet within its solar system.)---------Technically, there are no "cheats" on Poptropica, because the games are played on the site's servers and cannot be affected by programming changes.However, there are special items and effects available using the existing programs. And various sites including WikiAnswers provide hints and solutions to Poptropica games.(See the related question for some items and specials.)(To see all Astro Knights questions, type Astro Knights in the ask bar above)
