BANANA FORMULA (12 segments)
Professor Bermuda Schwartz invents a silent explosive called Hushaboom. Boris, disguised as a fruit peddler, steals the formula and writes it inside a banana. Bullwinkle wants to buy the banana, and Boris, always ready to make a buck, sells it. Since Bullwinkle can remember everything he ever ate, all is not lost.
Yup, Rocky and Bullwinkle
