I have gone through the shop and hidden 10 skull prims.
Inside each of these skulls is are hair styles, well more specifically the halloween releases from the last two years, all recolored into four new limited edition halloween colors. Each skull holds a different style and there are 10 in total. If you can find the skulls, they are free to buy, but they will only be out till halloween, thats two days! The 1st of November I will be picking them up.
Where are they? Of course I'm not going to tell you, that would take all of the fun out of it! But I will give you this hint. All the skulls are on the main island. Thats the island that houses the shop. They will be inside the shop and outside, maybe in the trees, maybe in the water, under things and over things, be sure to check everywhere!
Also please, please don't IM me asking where the skulls are, cause I won't tell ya! ;P
Happy Hunting and Good luck!
