The "Best Dressed" game has another problem.
When you hover your mouse over it, it might say "Online" for some reason.
But for most people, it won't load all the way and just shows the screen.
Also, I emailed Animal Jam about the tail item.
This item is Elf Tail Armor. Here is their response:
"Dear Fauna Toughclaw,
Thank you for contacting Animal Jam Support Headquarters, and might we add, you sure have a wild taste in Jammer fashions! it looks to us the item you're inquiring about is the Elf Tail Armor. Unfortunately, this item was removed from the shops in Jamaa to make room for more super awesome items all Jammers can enjoy, but since you like it so much, we'll be sure to pass your message on right away. Now, with so many ideas flying in, we can't promise this will come true anytime soon, but you can definitely count on us to keep our paws crossed for you.
In the meantime, we know many rare items like the Elf Tail Armor are pretty popular, but have you checked out the other fabulous accessories currently in Jamaa? Animal Jam Headquarters is always adding and removing items in the shops, so you just never know what will be "rare" next! In fact, you may just be able to purchase it now!

All the best, and play wild!

They might bring this item back sometime like super later.
