This is a themed drink that was created by Starbucks fans and is not an official Starbucks menu item. It is inspired by the character "The Child" from the Star Wars series "The Mandalorian," which fans affectionately call Baby Yoda.
The drink is typically made with a blend of matcha green tea powder, caramel syrup, and vanilla syrup, which gives it a green and brown color resembling Baby Yoda's appearance.
