Berrypuff

In Genshin Impact, Berrypuff, also known as 呜呜葡萄, is an adorable Blubberbeast that players can discover in an underwater aquarium located in the Fontaine region. This little creature requires your care through a time-gated questline where you'll help it grow. The quest is divided into five stages, each requiring a seven-hour wait in real-time to trigger the next part. Players are tasked with feeding Berrypuff fish, rescuing its friend, and defeating enemies threatening it. Upon completion, Berrypuff will grow into a strong Blubberbeast and return to the wild, leaving behind a Luxurious Chest and a hidden achievement called 'Blubby, Chubby, Creative Evolution'. This quest is not only fun but also provides ample rewards, making it an unmissable part of exploring the Fontaine region.
