A portion of my story's power system revolves around something called a Spirit Contract. It allows a person to access the characteristics of any one animal. It doesn't matter if it's living, ancient, or mythical. Therefore I have to do research on literally hundreds of animals (including insects).
Anyway, I've learned that certain species of penguins are the biggest predators on the planet (I'm talking about the Chris Hansen kind). It doesn't matter if they're young, old, male, female, dead, the ground, or a completely different animal altogether. Some penguins will literally stick their pool noodle in ANYTHING.
Now I could go on for paragraphs about the animal kingdom, especially insects. (My God the things I've learned about insects.) But I think I'm happy with ruining your view on penguins.
