tomorrow at 3pm EST, there will be a special litter drop. While this special variation is possible to be found in explore, this is the ONLY time they will EVER be dropped as a litter. (They will still be able to bred and found in explore, as well as available as customs, and once in a blue moon, a raffle). There are 6 available.
Because of their nature, these Skullies will cost 200 bones each. Please remember that you do NOT need to buy bones in advance as you have 24 hours to send a trade for them once you have placed your adoption form.
