Hello everyone! As you probably know PnF has available a couple charts in the Swap Shop to show the number of food/drink or gems you need to reach the next size. These charts are very basic to demonstrate the number of Greeter Cards, Silver Moles, or Golden Moles a user needs to create each size. Hopefully these may be of assistance to you.
If you are aiming for a large sized, or even full sized, items, don't feel daunted! A few users have already accomplished such feats!
