What a shock to hear someone talk right away in this cartoon! That almost never happens as these Pink Panther cartoons are 99 percent dialog-less.
Nonetheless, we hear a "Big White Hunter" type guy traveling with his guide in a jeep along the Africa plain mention about "a story about some guy who cornered all the animals in the thing called the Ark. If it can be done once, it can be done again." He builds the boat and names it after his girlfriend: "Nora's Ark."
The twist is that, unlike God producing all the rain, this guy sends fliers out to the animals, warning of a big flood and telling them to come to his ark! Pretty clever (with a few holes in the theory, but, hey, it's a cartoon).
Anyway, it works and two of all the animals trot into the boat....except the (one and only) Pink Panther. Where is he? The hunter goes after him, despite warnings that the PP is "taboo."
Overall, despite the ludicrous (and elitist) stereotyping of a big-game hunter and of a Texan, it's a fun cartoon with some nice artwork. The rain effect, and the ark and animals are all drawn really well.
The very last scene has the Panther utter a sentence, and we discover he's British!
