I don't have any prior knowledge of this specific addon, so I'll need to do some research. Let me start by understanding what a Minecraft addon is. Minecraft, especially the Java version, uses resource packs and datapacks, but addons are a bit different. They can use mods to add new features. However, "Morph into Anything" sounds like it might be a mod that allows players to transform into various mobs or entities in the game.
