Courage the Cowardly Dog - Season 3 Episode 19 Stupid dog. You make me look bad.
Tirohanga: A lady fish or fishonnary comes to take Muriel, Courage and Eustace back to "where they came from". It turns out they really go to an underwater bio-dome becausea all life originally came from the sea. These three fish judges annouce them guilty of uncivilized behavior (sipping tea, wearing shoes, etc.). So they put them in a goldfish bowl with gills that let them breathe underwater. They have to act like fish and even eat fishfood! Courage must save everyone.
