This is a brand new mod for Minecraft Pocket edition on Android. This mod is awesome, because it copies structures in your world and then pasting them somewhere else. It’s a new type of block which according according to the Minecraft wiki is an existing feature in Minecraft Pocket Edition but can’t yet (officially) be obtained. However, if you install this add-on you will be able to access the block and use it in-game. Enjoy playing!
