Diana's Fay Cookie is now available from Tommy in Market Place!
March 1st until May 30th, you can unlock new furniture, clothing,
and a special memory featuring Diana related to fairies. It costs the usual
50 Leaf Tickets, and it should be possible to acquire these cookies
from Tommy for 5000 every so often. There is also a 5 pack of the
cookies that costs 250 Leaf Tickets and grants 5+1 stamps.
Additionally, due to a successful retweet campaign, you can pick up free cookies (2 x Apple's Glazier Cookie, 2 x Poppy's Cocoa Cookie and 1 x Diana's Fay Cookie) between March 11th and April 11th.
Finally, there are special goals available now, between March 5th and April 22nd, in which linking your Nintendo Account to Animal Crossing: Pocket Camp will net you Leaf Tickets. There are additional goals related to completing animal requests that will give you Leaf Tickets and Sparkle Stones.
