Courage the Cowardly Dog

Katz Under the Sea is part one of the sixth episode in Season Three of Courage the Cowardly Dog, preceding "Curtain of Cruelty".

The episode was produced in 2001 and premiered on Cartoon Network in the United States on June 21, 2002.


Since Eustace is being so grumpy and demanding, Muriel and her dog Courage decide to escape from their everyday life for a while and go on a submarine vacation. However, the submarine is run by their arch-enemy Katz, who says no dogs are allowed on board. Courage disguises as a ventriloquist's puppet and switches places with the real puppet in a briefcase in order to sneak aboard. Meanwhile, Katz makes Muriel a maid and asks her to make tea. Muriel finds a bomb in the tea, and attempts to tell everyone, but this leads to Katz putting her in a cell. Upon hearing of Muriel's capture, Courage tries to seek help, but to no avail, as everybody is enjoying the cruise. Eventually, Katz gets thrown out of the submarine and eaten by a shark, while Muriel and Courage decide to go back home. When Courage hears the radio (because he and Muriel are tired in going to a vacation) he uses a tank to destroy a radio and laughs.
