They are all free it is a design hunt at this link http://www.kittykittyproductions.com/
Just click on the link and then click on a christmas hunt then read the pages and move your mouse around the pages until the pointer cursor becomes a finger pointing the click and DL the sprite alpha

The whole alphabet is free just go to the site and do the hunt. Run your curser all over the pages and when you see the hand appear there will be a letter. Good luck.
