How to swap
Select Gems, Food pics, Drink pics, or Decorations from the menu above. You can swap 5 gems, or 12 of anything else, for one of the next size up.
(There is no facility to swap items for the next size down).

How many items does it take to size up?
Below are two charts showing how many foods, drinks, decorations or gems it takes to make other sizes! (For "Decorations" use the "Food and Drink" chart).
