Do absolutely whatever you want with this thing. It will be hilarious if people actually pay money for it, but please don't sell this. Absolutely not. Because that would violate the MCreator Terms and Agreements thingy that says you can't. So don't.
Just go make your own mod if you want to edit this thing. It took me maybe an hour. About as long as I've spent publishing the danged thing. If you really want to make this a dependency for your mod, just message me or something with a decent reason why, and I'll fax you the MCreator workspace files.
But seriously. As with all of my mods, they really aren't that special. They're just not. And you could probably put something equal or better together in the same time. Trust me. Splicing code and/or learning tools is easy. Its how I mod New Vegas, Skyrim, Minecraft, and its how I learned to code Roblox Lua. Anyway, enough prattle from me: go hatch them dinosaurs.
