Vanilla Animals Expanded has a really big flaw.
It adds lots of new animals, being the Hedgehog one of them, but its in-game running speed is nowhere near accurate to a real one.
This mod aims to fix it and, thus, makes the game 169% more realistic and immersive.
It also may add some more Hedgehod related content.
And special thanks to the creators of Vanilla Animals Expanded, Alpha Animals and Numbers, as I used their codes as reference to learn how to create my own mod.
