Travel to Marvon Rivetseeker's workshop in Ratchet.
I managed to spy on what Muigin was doing, and he's actually growing the darn things over there!
I think the only solution here is to... no, not go talk to him... What are you thinking? The solution is to fight back!
We'll need the help of my friend, Marvon, who has a workshop in Ratchet. I'm sure he'll be able to create some sort of gadget that will help us.
