Bowling Ball Tuff Golem

My idea is to add the tuff golem, but with completely new features. First off, it cannot be pushed by other mobs or pistons, and other mobs ignore it. Even the warden! It rolls around when moving large distances. You can right click the golem to pick it up or place it down instantly. The golem itself can be walked on like a shulker. You can also hold right click to throw the golem as a bowliing ball! The golem also likes to stop other mobs, especially hostile ones, by pushing back against them. Finally, you can use this golem to climb walls. You see, when you right click with an empty hand, the last tuff golem you placed down will be instantly put in your hand, as long as it is within 3 blocks of you, and regardless of what direction you are facing. So you can scale walls and mountains by just spamming right click, and the golem basically automatically makes platforms for you. I should note this also means it sticks to falls when placed. If you leave the golem alone for a few seconds, it start randomly wandering around. It is also resistant to cacti and sweet berry bushes, because it is tough.
