In the vast expanse of the azure sea, a ship that has conquered the five continents and seven oceans cuts through the waves. The sailors, while cleaning, sing in unison, their lyrics mocking Captain Pete (voiced by Billy Bletcher). The rough and rude Pete rules the deck like a tyrant, driving the crew away before turning back to the cabin.

Enraged, Mickey breaks free, grabs a sharp pen, and prepares for a showdown with Pete. The strong and burly Pete, of course, doesn’t take the small and slender Mickey seriously. But he soon discovers that this clever, quick-witted, and brave opponent is not to be underestimated...
