Whoa its been a while since I been I was in the Village Greens but General Mayhem has been updated. Of course we still have the guards outside the purple mushroom house. But this time you no longer have to wait for him to show up outside.

1. click the purple mushroom house
2. choose your level
3. go inside you shall see General Mayhem inside

Of course like with any other boss you have waves. The waves consist of two genomes on easy, 3 on normal and 4 on hard with the inclusion of the mushroom tanks that shoot nuts.

If you defeat General Mayhem you do not receive "loot". I soloed easy and did not receive not 1 gold or charge orbs. It is simply to get credit to speak to a NPC that will give loot for completing the killing of General Mayhem.
