Der Maulwurf und der Regenwurm

One day, a little mole discovers that all of the other animals have a friend of their same species to play with except him. The food is starting to rebel. A fat earthworm escapes in a hurry, right under the mole's nose. He catches the earthworm, but it turns out that it's not a worm but another mole's tail. (Zlín Film Festival)
