The Spiked Collar is a members-only land clothing item. It was initially given out as one of the Monthly Member Gifts during July 2011. On August 8, 2013, the "Long" style was re-released in the Diamond Shop with new colors, but have not been in stores since. During June 23–26, 2016, the "Short" style was re-released in the Diamond Shop with new colors as part of the Spiked Sale.
The Spiked Collar consists of spikes attached to a circular band worn around the neck. "Long" Spiked Collars have a pattern of alternating large spikes and small spikes, but "Short" Spiked Collars only have one size of spikes. There are eight different color versions of each type (non-rare "Long", non-rare "Short", rare "Long", and rare "Short") for a total of thirty-two varieties.
The Purple "Long" Spiked Collar is not the same color as the Purple "Long" Spiked Wristband.
The "Long" Spiked Collar was originally named Spikey Necklace.
The "Short" Spiked Collar was originally named Spiked Necklace.
The "Long" Spiked Collars have more vibrant colors than their "Short" counterpart.
The non-rare "Long" Spiked Collars (along with one of the non-rare "Short" Spiked Collars and some of the Rare "Short" Spiked Collars) are the only variants in which the spikes and the neckband share the same color.
The non-rare "Short" Spiked Collars have a light blue tint on the spikes, whereas the Rare "Short" Spiked Collars have a variety of different spike colors.
When worn in the Adventures, the "Short" Rare Spiked Collar does 16 damage and the "Long" Rare Spiked Collar does 17 damage to destructible obstacles such as Phantom Webs as opposed to 10 damage normally.
Unlike the Rare Spiked Collars on which they are based, the non-rare varieties do not provide any extra damage when worn in the Adventures.
In the "Animal Jam - Play Wild in National Geographic" commercial, a horse can be seen running through Jamaa with an unreleased brown "short" spiked collar.
In Animal Jam - Play Wild, there is a den item counterpart to this, the Spiked Table.
