A Hatcessories are SPECIAL items that functions as both a Helmet and an Accessory. It can be either worn on the player's head or placed in the Accessory Bag. They grant +1✎ Intelligence for every SkyBlock year the player's profile has existed, but only when worn as Helmet.
The Hatcessories do not stack with each other and only one will provide stat boost and Magical Power.
The name Hatcessory is a partial portmanteau of hat and accessory.
Hatcessories are inconsistent with their names. The 2022 Crab Hats are the only Hatcessories specifying their year of origin in their title. Crab Hats and Sloth Hats are said to be "of Celebration", while the Balloon Hats are "Anniversary".
All hatcessories, except Balloon Hats, create particles around the player when worn on their head. Occasionally they also launch a firework as well.
Sloth Hats come in 10 variants, while every other Hatcessory only has 9.
If a player wears a Hatcessory on their head while keeping another different, or another of the same, in their accessory bag, they will get ✯ Magic Find from them both. The stats from Enrichments are also doubled this way.
