Do you have unwanted nest stuffs? just sell it in Gongs Pipenest ->Haggle Hut to get back your Mulch.
You entered the hall and met the seller Nab. He’ll give you a good price for your old junk! Just drag items to the hatch and press sell button.
For a example I sell precious something, Nab give me better price then he says “I’ve never see such rubbish in all my life! I’m robbing myself, but I’ll give you 159 Mulch’
For this case you will be given 3 options/deals (Accept, Take a chance, Decline) it’s up to you.
