Disney XD has released a new preview clip from the upcoming Star Wars Rebels episode, "The Forgotten Droid", and it features Chopper spotting an exact match for his missing, original left leg.
Official synopsis:
Accidentally abandoned at an outpost during a hasty escape, Chopper stows away on an Imperial freighter where he befriends an Imperial navigation droid, recruiting him to the rebel cause and receiving his help in finding a location for the much-needed rebel base.
This episode looks pretty laid-back. It's good to have a comic-relief character like this droid though.
The new episode of Star Wars Rebels premieres on Wednesday on March 16 (9:00 p.m., ET/PT) on Disney XD
