Ebrrrlurrgh! Hello, I'm a Desert Leaper. I'm actually a gerbil, despite looking like a kangaroo. The desert is a harsh place where very few survive, and I'm one of said few. I can store fat in my tail, allowing me to survive up to three months without food! When my body is full, I move by hopping bipedally across the desert like a kangaroo, but when I spend ages without nourishment, my body enters an "emaciated form" and in this form, I run on all fours. Ebrrrlurrgh!!!
