The Creators have just released the new Poptropica feature “Realms” – which is basically Poptropica Land, but now with separate worlds and an apparent universe that is yours to do what you want with. Check out the PHB’s Realms guide for an in-depth look on this new feature!
UPDATE: According to Poptropica’s Twitter, 1000+ Realms were created and 7000+ scenes were saved just in the first evening of the launch! They also tweeted this sneak peek of hats based on the various biomes, possibly coming soon…
There are 7 biomes (Forest, Snow/Ice, Desert, Swamp, Lunar, Fire, Crystal) – the latter two are members-only and the latter four are new. Each has its own ambient soundtrack (no more chirping bird noises!); plus, you can listen to the awesome main theme on Jeff Heim’s soundcloud:
