Tomorrowland Terrace is a restaurant located in Tomorrowland at Disneyland in Anaheim, California that is notable for its unique concert stage, which hydraulically rises out of the ground. It opened with the new Tomorrowland in 1967.

Sixteen or more children are chosen from the audience as Jedi Younglings to participate in a training session by the Jedi Master. They are provided training lightsabers and Jedi robes. As the master completes the instruction of a simple combination of lightsaber attacks to the children, Darth Vader, Darth Maul and a pair of stormtroopers appear. Each Jedi trainee faces off in turn with either Maul or Vader until the villains retreat back to the stage, outnumbered (there was, however, one viral instance of an 8 year old girl who, rather than fighting Darth Vader, instead opted to join the dark side with him, and was subsequently led to 'the Sith Training Academy' by the understandably flummoxed Jedi Master). The children, now Padawans, are congratulated on their mastering of the Force by Yoda, then return the training lightsabers and robe, and are given a diploma for their participation. A duplicate version of the interactive show also occurs daily, as a standalone event at the Tomorrowland Terrace in Disneyland.
