Control mobs plugin

Hello! I would like someone to please make me a Minecraft plugin that consists of controlling mobs. I know there's already one but I've got problems with it. It shows an error whenever I want to morph into the mob, and it also shows everyone in the chat what I've morphed into, so it's not very stealthy anymore. If someone would please make something as simple as running a command to control a specific mob; I'll morph into the mob and have all its abilities. Any title you want.

Version: 1.16.4

Thanks!
