Poptropican

"As we suspected, exposing objects to increased or decreased air pressure temporarily changes the shape of their bodies" 

Poptropicans
Poptropicans are small, neckless, human-like creatures that can run fast and jump high. Their heads float around, only to be held up by an invisible force. Their heads can also come off when angered (they fly up into the air and come back instantly, after a few bounces). Somehow, their hair is not completely attached, either. Their heads also catch up with them when falling, but not as fast as their body. Also poptropican seem unable to die proven by poptropica characters jumping off high buildings and surviving major crashes(Cryptids Island) without a scratch, though they can get hurt. However, in the comic Day Zero, explaining why the outbreak began in Zomberry Island, it depicts Poptropicans with normal sized arms, fingers, normal legs, feet, and the ability to wear shoes(Poptropicans have the ability to wear shoes, but they choose not to unless necessary (Wimpy Boardwalk Island). They are also immortal, can turn into vampires (or zombies) and can have super powers. They can have abnormally colored skin and hair. In the arcade on Museum Island, a Poptropican will lose all it's lives by simply falling or hitting an obstacle. The less you hit an obstacle, the higher score you get (Poptropica Adventures Nintendo DS). Poptropicans obviously aren't the only ones inhabiting Poptropica. characters in the style of Greg Heffley Nate Wright, and Charles Schulz inhabit Poptropica(Wimpy Wonderland Island, Wimpy Boardwalk Island, Big Nate Island, Great Pumpkin Island).

Islands
Poptropica's islands are were poptropicans can discover and uncover mysteries.You can get a medal and 50 credits (Before they were 100 credits!) when you finish an island. In some point of the adventure, you recieve or find an item that you can use for later on. Some of the items you can even wear around the island! But they're specific items that you cannot use in another island. There is a map where you can see the names of the places you visited on an island. Right under the map at the left side there is a button that will restart your island that you're on. There is also multiplayer rooms to friend, chat, and battle by playing games with other poptropicans from around the world. Sometimes there are advertistments in the main street. They are quests that instead of credits and a medal, when you complete the task you get prizes that you can wear or use around any island. Currently they're 32 islands.  'Below are some of the islands that you can go.
