Kingdom of Knuffel is an avatar and adoptable pet (knuffel) site with an awesome forum community and devs. You can even create your own wild knuffel!
Read more about digging for materials here. This list excludes avatar item drops. To dig, go Knuffel > Candy Island. To view your material inventory, go to Avatar > Wardrobe > click the Diamond icon.
This is the accumulated data of months of digging but there’s definitely drops I’ve yet to obtain so this list is still WIP and will be updated periodically. List by moshimushi.wordpress.com, if found elsewhere, it’s been stolen.
