Features:
- One of the standout features of this addon is the attention to detail. For instance, when you spawn mobs with an egg, they perform a little pop-up animation, a small but delightful detail that adds to the overall experience.
- The addon also includes updates and improvements to existing mobs. For example, the ducks, banana ducks, and anglerfish have been remodeled, and more uses have been added for anglerfish, yutyrannuses, endercats, and mergeese.
