Also known as: 塵歌壺
The Serenitea Pot or Realm Within is a system in Genshin Impact that allows a player to decorate a home and the realm surrounding it. Players interact with this system using a gadget of the same name that is given to them by Madame Ping.
Tubby and Chubby are two Teapot Spirits who appear in this realm. Players can also add any of the characters they've personally obtained (aside from the Player Character) to their teapots as "Companions" which allows them to idly increase their Friendship Level with those characters.
