Bundles and Camels

I think we should be able to attach bundles to camels. Possibly with a left click, similar to how you would store and access books/items on a book shelf/shelf. 2 or 3 on either side would be ideal. This could potentially extend to other mobs as well such as happy ghasts as a more functional option. I also think it could be fun to extend it to less conventional mobs like frogs being able to hold one bundle, or birds.
