Installation:
Download and load up Mobs Properties Randomness by Insane96MCP and "Mine Mine No Mi" by WyndFTWz. Make sure to install the required mod for Mobs Properties Randomness called "InsaneLib."

Load up a world in the modded Minecraft. This will create a config for both Mine Mine No Mi and more importantly, Mobs Properties Randomness.

Once done, go back to the menu screen and go into its .minecraft folder. This can easily be done by opening the resource packs folder in Minecraft and going back to .minecraft in the folders that open up. If you still don't know how to do this, search it up somewhere and a tutorial will come up. Knowing how to do this is essential to modding.

When you're in your minecraft installation folder (.minecraft), go inside the "config" folder. In the config folder you will see a folder called "MobsPropertiesRandomness." Go inside that folder.

When you open that folder, drop the two folders (mobs, presets) that are inside my "Stronger Captains" folder inside the MobsPropertiesRandomness folder. This should add every json file I have created in the "mobs" and "presets" folders.

Done! Load up your world and conquer the seas.
