You thought your ex-girlfriend was a creep? Ha, just kidding, you’re on the internet.
This Mod packs a ton of stuff. As the name implies, you get tons of weird creepy and fun Mobs. Take for example the Floobs. They are aliens that have spaceships and ray guns and the whole shabang. Then you have the ManDog, a dog looking human hybrid that will play frisbee with you!
Here is a nice review of the MoreCreeps & Weirdos Mod.
