Legend of the Three Caballeros season 1 episode 11
Episode title: Thanks a Camelot!
With the Caballeros back among the living, Xandra takes them and the nieces to Camelot to get them some proper "hero training" from King Arthur himself, but the King's purely-motivational training leaves a lot to be desired when the nieces accidentally summon a dragon. Meanwhile, Sheldgoose breaks into the Caballeros' cabana to steal back the Spark of Life. Though he is foiled by Ari and the bear, he manages to steal the amulets instead.
