I believe we only gift at Valentine's... we have had heart shaped candy gift boxes,2 size letters as gift boxes and these actual gift boxes ... remember to keep a few of the boxes for later to use as an item (they won't give out gifts but they remain a gift box item).
You can check out the Events category on the Forum page for past events. I also love the Pengwing events and not everybody does, but I really have fun when our Easter event has us finding Easter eggs or when our events have us finding helpful Pengwing's that give us feathers or items.
