No one is saying exactly why, but it was probably because they didn't want everybody to have to work on the US national holiday (MLK Day was January 17, 2011).
Normally the games had been coming out on a Thursday (since Nabooti Island in 2008). However, with Christmas on a Saturday, the game was scheduled for the Tuesday before (December 21), then rescheduled for Monday (December 20). Since the normal Early Access is exactly 4 weeks, the release date would have been Monday, January 17, 2011. This was altered for some reason to Tuesday January 18, 2011 after the Monday date had already been promulgated.
As of its release date of January 17, 2011, the most recent island was #16 - Cryptids Island.
The 15th island was Great Pumpkin Island (October 14, 2010), immediately preceding Cryptids (January 18, 2011).
Cryptids Island is the 16th Island of Poptropica, opened to general use on January 18, 2011. The quest is to recover scientific proof about cryptids - legendary creatures that may or may not exist.----------------------------------------------------------There are no "cheats" as such on Poptropica, but there are solutions at the related question below. There are also special items in Poptropica at the related question.
