Jade Cocoon

On the first level before blue cocoon master house where you find the key with the two snakes.
If you keep returning there and kill them you get rewarded with the health walnuts, which increases your levels easy way to kill them is get your minions to footstomp them.

To not be attacked by crouching minions, walk backwards until you get off the screen. 
This only works on the minions that are crouching, like those dog thingies that have armour on their backs.

In the level,right before the hut, you will see someone dancing, go to this person and ask her if she likes you. 
If she says no, which is really rare, she will smack you after you are done talking to her. 
if she says yes, she will take you to a hidden level, which has a knowledge block#9 in it and 10 minions.

This is a code for jade cocoon you talk to Koris, ask about capturing his orders and after you capture the minion,he gives you Arpatron for free, ask about attacking and defending follow his orders and you keep getting free mugwort.
Do this until you are satisfied. Submitted by:
