There is a town where only birds inhabit.
If the Birds got a prey, they share it in the middle of town.

One day, a pelican caught a large gray mullet on the way of hunting.
A pelican had greed on way of returning toward a town.

“I want to eat this alone not to share. But where should I hide this?”
A pelican considered and decided to hide in his mouth.

A pelican couldn’t tell anything because of a left gray mullet, even though he ate satisfactorily.
He had to avoid friends not to answer even if they talk to him.
Whenever he got food ever since, he hide it in his mouth.
This made him lose his friends and made his chin long.
