Suddenly Nanabush realized the pumpkin has arms and legs. The pumpkin floats up to become the moon.
Then Nanabush yells at the moon, "you come down you silly pumpkin"
The pumpkin refuses and scared everyone in the town by coming down as a person saying "Croook, craaaak, clloooook" knocking over kookums and mooshums
So Nanabush comes and he says "poocon, go back to the pumpkin patch" and makes a ferocious face.
So, the pumpkin runs away to the pumpkin patch and is never seen again and that is why we have Halloween.
