This cartoon short is basically about penguins and there are several little penguins investigating a house. A woman penguin nearby tells them that "Curiosity killed the cat" in a song version, going, "Curiousity killed the cat, Curiosity did just that" &c. The little penguins pay no heed and fall into the house from the chimney and they nearly kill themselves. Have they learned to never be too curious again?
This whole cartoon is silly nonsense, yet it had a message, "Curiosity killed the cat". This cartoon was only made for children, to teach them to not be curious. It is very unlikely people over the age of 13 will want to watch it again, unless they like the little song.
The only reason I like this is because of the song and the has a weird ending, which is quite funny though very surprising.
I only recommend this to old cartoon enthusiasts (I mean cartoons that are old, not enthusiasts that are old) and to parents who want to make their children learn that "Curiosity killed the cat". Enjoy "Peeping Penguins"! :-)
