Skins are different styles of avatars players can use in the game. They were added in the Sounds Good update. To use skins, players have to share starve.io on Facebook or Twitter. When done, players will be able to choose between all of the skins, as well as the accessories.
Skins can be accessed at the top right corner of the game's starting screen after sharing. They come in various different colours and emojis including the original "blue" one, which stayed in the game for the longest amount of time (was from the first release). Accessories can also be optionally added to any of the skins (there are no theme limits).
Accessories are small features which can be optionally added onto your character. They are separate and independent from skins. There are currently 8 of them - a pirate eyepatch, a monocle, a bandage, a pair of glasses, a peace tattoo, blush, a flower and a set of horns. Access to accessories is granted simultaneously with skins, by sharing starve.io on either Twitter or Facebook. Only one accessory may be used at a time. Like skins, accessories serve no purpose other than to alter your appearance. Accessories were added in the BAKERS ARE YOUR BANKERS update.
