Penguin Dances

While browsing on Pinterest, I came across this purportedly USA folk dance, apparently being done in Italy:


As near as I can tell from my almost non-existent Italian, it's meant to be done with 5 couples, corresponding to 5 times thru the music, so that each couple gets to be the "protagonist".  I don't think we'll be adding it to our repertoire anytime soon, though.

But then in the sidebar on youtube I came across an entirely different penguin dance, which basically looks like the bunnyhop, but to much catchier music, and seems to be done at weddings all over the world, and all over social media:



There's a blog dedicated to it: https://penguindancemania.wordpress.com/
Which includes this German video from 1965 of a dance called "Letkiss", along the same lines:

If you try to look up "Penguin Dance" on Wikipedia, you get routed to the Bunny Hop:

Which also refers to it by the Finnish name "Letkajenkka" -- and you can find a lot of videos with that music (as in the 1965 Letkiss video).
