Poptropica Realms

Poptropica: Land, previously known as Poptropica Labs, is an experimental members-only feature on Poptropica. It is essentially a sandbox that enables you to create structures and change the landscape to your will.

Explore
Explore is the icon with the compass at the bottom-left part of the screen. It gives you the option to explore the surrounding area just like in a regular island,

Mine
The Mine function takes the form of the hammer icon at the bottom-left corner of the screen. It allows you to use the Svadilfari to destroy objects. Destroying natural objects also allows you to obtain Poptanium, which allows you to level up and unlock more building materials. You can toggle between mining background and foreground objects with the background and forground options next to the biome icon.

Create
The Create function is the paintbrush icon at the bottom-left corner of the screen. Clicking on it, and then clicking on the plus icon that appears allows you to search through the Create menu to use different building materials. There are three segments in the Create menu, natural, construction and props. You can unlock more objects by obtaining Poptanium and leveling up. You can also toggle between brush sizes and erase previously used materials.

Biome
The snowflake icon at the bottom of the screen allows you to toggle between biomes, or environments. So far, there are three biomes available, forest, winter and desert. The desert biome can only be unlocked at 125 Poptanium crystals.

World
Clicking on the World icon gives you four options. Save the world in a file, load a previous world, start a new world or share a world you created.

Creatures
There are many creatures that inhabit the world. Some are friendly while others are hostile. Hostile animals have red eyes and will attack you, causing you to lose health. Friendly animals will not affect you but will sometimes follow you from screen to screen. All creatures can be killed by dangerous materials that you add, like thorns or cacti or lava. Creatures can vary in size and appearance, and some are capable of climbing ropes.

Trivia

 * This feature is very similar to the game Minecraft, in that it enables the player to build and destroy objects in a square-by-square fashion.
 * When you save a world, only the areas which you have altered are saved. Areas you haven't altered still change randomly.
 * Svadilfari, the hammer used to destroy and create objects, is named after Svaðilfari, the father of the eight-legged horse Sleipnir in Norse mythology.
