The title's a play-on-words of the phrase "Puss in Boots", and is similar to Cruise Cat (1952), from the Hanna-Barbera era.

Tom is puzzled to see a second captain, but all the same must salute as Jerry-captain prances up the steps.

He notices the captain is moving slow, there is a broom where his head should be, and then spots the body of the mouse poking out from under the uniform.

Jerry turns white and frantically runs into his hole and shuts the volume closing door.

Tom is laughing himself silly until he sees the real captain falling off the edge of the ship because the ramp has moved.

Tom crawls through shorter widths of pipe in order to catch Jerry, and when the chase exits the plumbing, Tom is compressed into a cylinder with legs barely a centimeter wide, forming himself in some kind of a walking stick.

When Tom realizes this, he takes a deep breath and uncompresses himself, briefly looking like a more monstrous feline in the process.

Jerry has opened the crate of cheese and is munching away when Tom thrusts the hose in his face.

He blows a whistle, salutes the captain, and does the dance jig to the audience at the end of the cartoon.
