Marty the Ostrich and Marta the mole are best friends. They both live in a tree-town called Leaves and Roots. The only thing is: Marty lives up in the Leaves and Marta down in the Roots. The two neighborhoods, situated one above the other, exist in perfect harmony but on a daily basis, the inhabitants keep to themselves. Or they did... until Marty and Marta started to mix things up!
