How rested would you feel if you took 10,000 naps a day? Chinstrap Penguins in Antarctica spend their days taking MICRONAPS, each around 4 seconds long. To learn why, Lulu meets one (played by Songbud Alan), who explains how micronaps help them conserve energy and protect their babies from “sky pirates”! Then, in a badgermania, penguin scientists Dr. Eric Wagner and Dr. Dee Boersma answer your questions! Why are penguins black-and-white? Why is their poop pink? What might they dream about? And we learn that what may look like laziness… turns out to be an evolutionary superpower.

Don’t sleep on these articles, maybe read them before your next nap:
