It's Bullwinkle Vs. Boris as the Big Cheese in a musical contest to win the affections of the metal-munching mice. It looks as if they were returning to Boris, but just threw him into a lake, then Bullwinkle began singing again, and the moon mice returned to him. Unfortunately, Bullwinkle was out of songs, and the moon mice crowd was getting restless. Just then, Boris came posing as Colonel Tomsk wanted to put Bullwinkle in a concert at Collosum Stadium, and all of the moon mice get in for free. Bullwinkle receives in his honor an electric ukulele; Boris plugs it up to one of the columns in the stadium, which was connected to all of the others, so that the first chord Bullwinkle struck would be his last. Natasha points out that the moon mice would be destroyed too, but Boris had complete confidence that more were being made on the moon. On the moon, Mr. Big received news that not another moon mouse could be made due to a shortage of the material. Mr. Big wasn't worried, and left for Earth to see the progress of the mice. When Bullwinkle tuned the ukulele, the dynamite acted as rockets and shot the stadium up towards the moon, which crashed into Mr. Big's ship on the way. The moon mice were back on the moon, and Mr. Big was foiled.
