Intro. (Minecraft mod that should be banned) anyway.... Jenny is from the famous, strangely famous, Jenny mod where you add this unusual character where instead of your objective being to help, it would be to hinder your journey. She is very greedy and would do anything for rare jewels like diamonds, emeralds, etc. Her goal was to defeat the end dragon, but she will probably follow you until she gets what she wants.
