It's Bacon Berry's birthday and the crew is excited to celebrate but their spirits are dampened when they realize that Phil bought the wrong gift for the occasion.
Lettie has so much work to do as the Captain of the Calypso that she can't join in the fun with the rest of the crew, so Lemo comes up with an invention to help.
When the Calypso Crew think that Lettie is not fun enough, she asks Captain Tubular to teach her how to become a Fun-Captain. Lettie gets carried away when she decides to show her crew just how fun she can be.
The Calypso Crew is on a secret mission to escort Big Blue superstar, Lea, to her concert. Lettie uses this opportunity to make her rival Mira Clearwater jealous and must deal with the consequences of her decision.
