If you would like to turn into a mob and get his ability back then Mod Advance Morphing will help you and you will have access to all the images of the mobs that are in Minecraft PE. To get the appearance of a mob, you first need to defeat him, then in a special menu to choose its appearance, as soon as you turn you will immediately see all of his abilities. Another interesting feature of Mod Advance Morphing for Minecraft PE is the ability to save all images and change them whenever you want. For example, if you need to cross the river, you may turn to chicken and fly it, and if you need to climb high, steep wall, then nobody better than cave spider for this task to be found.
