Katz Under the Sea is the {{{numInSeasonWord}}} episode in [[Season {{{seasonWord}}}]] of Courage the Cowardly Dog. It aired {{{airDate}}}.


Courage and Muriel go on a submarine vacation, since Eustace is being grumpy and demanding. However, the submarine is run by Katz. Katz's submarine does not allow dogs, so Courage disguises as a puppet to get in and let the real puppet out. Katz made Muriel a maid, and asked for tea, but Muriel found a bomb in the tea. Katz puts Muriel in a cell, and Courage tries to seek help, but to no avail. Eventually, Katz gets sucked out of the submarine and eaten by a shark. Muriel and her dog decide not to take anymore vacations.
