I'm new to the forums so I don't know if this is the right place to put this but I seen the phantom in the 1.13 snapshots and thought it would be cool if there was a way to ride it, like many if you could find their nest, take a egg raised it and when it grew up you could put a saddle on it and ride it.
If you intend on posting to suggestions, you'll need to put a lot of work into making your idea presentable. People there take things very seriously. If you would like help on the specifics (how exactly to ride the phantom) or presentation (pictures and intro/conclusion) you could PM one of the more established suggestors for advice. I'm sure they'd be happy to assist you.
