No, there unfortunately wasn't some sort of international competition to determine the world's cutest frog. But if there were, this little ball of squeak would definitely win:
This is a Namaqua Rain Frog. These little guys are found in Southern Africa (not in a Poke Ball, as previously assumed), and their roly-poly froggy bodies and adorable squeak are actually supposed to be defense mechanisms. Defense? From what? OUR LOVE?!
