Did you know that the character of Grogu was conceived by John Favreau who wanted to explore a new character from Yoda's species at the beginning of their journey while in training, in contrast to Jedi Master Yoda, whose story ended in return of the Jedi. When Favreau discussed the character with executive producer Dave Filoni, the latter drew a rough sketch of the youngling on cocktail napkins. Favreau explained that he wanted the character to have a lot of wrinkles and that he wouldn't look too cute, and multiple members of the Lucasfilm art department then worked to refine the image created by Filoni. Christian Osman would go on to finalize the design of Grogu, which Favreau loved as it looked cute but also looked a little weird.
