Stream Avatars

Stream Avatars are the tiny little guys at the bottom of Sleepys stream. They wonder around, say what you say, and are essentially you. You gain a stream avatar just by showing up to a stream. You gain Experience by hanging out in streams, catching rare candys that spawn, and winning minigames. You can then use that experience to buy a new avatar, or equip pieces of gear to your avatar! There are tons of options!

Avatars

There is also Kirby, Isaac, Duck Game Duck, Pikmin and Bulborb, Dragon Quest Slime, Among Us Crewmate and Shy Guy. More get added all the time, and you can even pay Channel Points to get one made! If you do this you unlock all of the parts of that character you got made and the rest is available on the shop for everyone.
