To dip my toes into using the Mythruna API I decided to make a simple, cool plugin that I had seen before: the cowsay plugin. I made this in less than an hour but it was very helpful to start to learn the API.
This is what it does. It has an ASCII cow that says what you want it to. This plugin works in single player and multiplayer.
Commands:Single Player: /cowsay (what you want it to say)
Multi-player: ~cowsay (what you want it to say)
