The Addams Family (1973) 1x12

The Addams Family take their first ocean voyage, but the sight of Ali the Alligator and Ocho the Octopus dancing has every passenger aboard spooked; so much so that they jump overboard. The crooked Lefty and Joe promptly steal all the valuables aboard as a result, but the Addamses are soon in hot pursuit of the thieves as they attempt a getaway in a speedboat.
