Hey so I'm making a new campaign and the premise is there's this crazy guy who has been experimenting on rats. To reflect that I've been making a bunch of different types of rats to fight throughout the adventure. The adventure is for characters level 1-3 so real low level characters. I'll be posting more as I design them. Let me know what you think thanks.

I'm also knew to this forum so let me know if I posted this in the wrong place or anything. Thanks again.
