Ertle - Earth
The name "Ertle" rhymes with "turtle," and where do you find these shell-backed reptiles? On Earth, of course—Ertle’s favorite planet and our little blue home in space! Ertle loves Earth because it’s the only planet in our entire Solar System family upon which life can be found… and life is everywhere here, isn’t it? It seems that under every rock, atop many mountains, and even deep in the deepest parts of the ocean, some form of life can be found on Earth.
Ours is truly a very special planet. And Ertle is a very special Cosmic Cub, too! He’s the leader of the pack, a good-natured and lovable cub who has the most fun when he’s helping others. Keep up the great work, Ertle!
