Bella
This mod requires Quilt Loader and Quilt Standard Libraries

The Bella mod offers players one very interesting feature - decorating animals with bells. This function works with most creatures that have a head separate from the body and use the standard model. Interestingly, the mod is also compatible with mobs from other mods, so you can experiment with various creatures.
If you want to remove a bell from an animal, simply right-click with an empty hand while holding Shift. You can also use string on an animal with a bell to disable the ringing sound.
