Kratts' Creatures S01E13 - Weird Creatures

In Australia, Chris and Martin go in search of egg-laying mammals, some of the weirdest creatures on the planet. But Ttark reminds Allison and the guys that "weirdness" is humans applying human rules to the creature world. On the trail of egg-laying mammals, Chris and Martin discuss other creatures humans think are weird: thorny devils, squirrels that fly, and underwater animals that look like plants.
