Grogu has appeared in every episode of the first two seasons, with the exception of " Chapter 15: The Believer". Prior to this, the character's official name, as used in subtitles and captions, was " The Child". The character's real name was not revealed until " Chapter 13: The Jedi", which also explained that Grogu was raised at the Jedi Temple on Coruscant during the Clone Wars.

In the series, the protagonist known as " the Mandalorian" is hired to track down and capture Grogu for a remnant of the fallen Galactic Empire, but instead, he becomes his adoptive father and protects him from the Imperials. He is a toddler member of the same unnamed alien species as the Star Wars characters Yoda and Yaddle, with whom he shares a strong ability in the Force. Grogu, colloquially referred to as Baby Yoda, is a character from the Star Wars Disney+ original television series The Mandalorian.
