seed that left his pumpkin

Nut is a seed that lives a safe and quiet life inside his pumpkin with his brothers and sisters. But he, unlike the rest of them, is convinced that a "e;World Out-There"e; must exist. Even though everyone tells him not to, Nut decides to overcome his fears and leave the pumpkin to see what awaits him outside. An ant, a cicada, and a magpie help him to discover the world they already know well - but what if the World Out-There is just another pumpkin to find a way out of?
