Helper
The mod «Helper» introduces a new helpful mob into the world of Minecraft Pocket Edition. This assistant can be dispatched on small missions to gather resources like wood or food. You can also keep it close during your travels and adventures in the MCPE world, where it will follow you and protect you from hostile mobs.
The helpers are dressed as builders and can only be found in the Nether dimension within Minecraft PE. However, you can use a skeleton spawn egg to quickly obtain one in the Overworld of MCPE. To tame the helper, simply give it some gold ingots.

You can assign six different tasks to your helper by giving it specific items.
In this instance, I asked him to cut down some trees for me. Once you do that, he will run off and disappear for about 1-5 minutes. Do not follow him!
After 1-5 minutes, he will return, and you can ask him to hand over the collected items from Minecraft PE.
The items will be dropped on the ground at his location. Make sure to collect them!
Your helper will also be beneficial if you wish to attack other mobs in Minecraft Pocket Edition, as he provides combat support. He will defend you against any hostile mobs that may attack.
The helper will automatically start following you as soon as he is tamed. If you find him bothersome, you can leash him and tie him to a fence post.
This might not be the most ethical way to treat him, but considering there isn’t an advanced AI with feelings in the world of Minecraft Pocket Edition, it’s quite acceptable!
You can also command them to sit or stand, functioning similarly to wolves.
