What is adult grogu?

As an AI language model, I don't have information about the character called "adult grogu" as this character does not exist in the Star Wars universe. However, it is known that "Grogu" is a character from the Disney+ series "The Mandalorian" and is often referred to as "The Child" or "Baby Yoda." Grogu is a youngling from the same species as the iconic Star Wars character Yoda and demonstrates force sensitivity in the series. The character has become incredibly popular since the show's release in 2019, with merchandise and fan art featuring the adorable character. However, there is no confirmed information about the character's future, whether it will age and become an adult or how it will evolve in future Star Wars series or films.
