About to sail his brand new liner from San Francisco to Hawaii, the captain makes it clear to mascot "Thomas" that he's for the yardarm if so much as one mouse makes it aboard. Now of course this isn't going to deter the guitar-playing "Jerry" and soon the usual living room slapstick antics between the pair take on a distinctly nautical air. As ever, it's the mouse who keeps the upper hand - until they visit the ship's cinema where their "Texas Tom" cartoon is playing. Truce? Of course not - well not for long, anyway! Featuring a lively score and a rather shocked seagull, this is quite good fun for seven whole minutes!
