Spiked Collars are a member only land item. Spiked Collars were the first ever monthly member gift. A rare version can be obtained by trading, a monthly member gift, or won in the adventure,
The Forgotten Desert. There are 2 types of spiked collars. They are long and short. Long spiked collars are considered more valuable and rare. There are non-rare long spiked collars that are available at the Diamond Shop for 3 diamonds and come in different colors (long spikes only). Spiked collars are a very wanted item on Animal Jam. A lot of jammers think these are beta because they are so rare and valuable, and they aren't, they are just a monthly member gift. Spiked Collars lost a lot of their rarity because you can win them on the adventure, The Forgotten Desert. There is also a Spiked Wristband that matches each Spiked Collar. The wristbands were also a monthly member gift. They aren't as valuable as collars but they still are very wanted. The wristbands are long and short as well and can be bought in the diamond shop as well for 3 diamonds (only long wrists). (Rare spikes are a lot more valuable then non-rare spikes since you can buy non-rare spikes in the diamond shop for 3 diamonds. Which Rare spikes are no longer available and are very old.)
