Accessories are optional cosmetic items for the player's character. With this option, the player can add an outfit or decoration to their character. Accessories come in multiple different forms from antlers and crowns to outfits and kigurumis.
Almost all accessories originate from an event, and following the event's conclusion, the cosmetic will either remain seasonal or become nonseasonal. If the accessory remains seasonal, the player can either only unlock the accessory during that event or the accessory is always available but requires special currency that was only awarded during that event. Each accessory also has a different unlock type. Some accessories can immediately be equipped by all characters after being unlocked, some can only be equipped by specific characters once unlocked, and others must be unlocked individually for each character. Some accessories have also not been added to mystery bag's contents, and thus have not become collectible again since their introduction into the game.
There is one additional category of accessories, known as glasses. Glasses function identically to other accessories, with the key difference being that you can equip them alongside standard accessories.
Standard accessories are represented in the cosmetics menu with a icon. Glasses are represented in the cosmetics menu with a icon.
