A little while ago I was asked by a publisher I work with in the US - Blue Apple - to create an anniversary apple to help celebrate their 10 year anniversary. I have worked with Blue Apple on two titles - 'Monster be Good' and 'Monster Needs One More'. See all the Blue Apple Anniversary apples at this link:
