Thanks a Camelot Legend of the Three Caballeros : Season 1 Episode 11

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.
