This is a simple mod that adds a Kissy Missy mob. Right clicking on Kissy with beetroot in your hand gives you a chance to tame her, and once you do so successfully, you will be able to ride her like a faster horse.
Note: In the video I say you need to cover the incubator with pink wool. This is outdated, you need to use pink stained glass.
Kissy is a generally a passive mob, and does not go out of her way to cause harm, but if she is angered, she can cause devastating amounts of damage. At the moment, Kissy doesn't spawn naturally, but must be grown by incubating a strange egg.
Strange Egg Video Showcase:
You can craft a strange egg with an egg, a saddle, a nametag, and 6 wool.
To incubate the egg, simply place it on a magma block, surrounded by glass on all sides, with a pink stained glass on top.
Kissy Missy uses the Huggy Wuggy model and animations from the Poppy Playtime IC mod, which it needs to run.
