There was a panda.
And every day, first thing in the morning, he was eating cookies.
Until one day, he got very bored of cookies, and decided to go to the pond to eat some fish. He was tired of eating lots and lots of cookies.
And because of that he went to the pond and ate some fishes. He was so full of fishes, he decided to eat cookies again, and lots of sweet stuff like marshmallows.
And because of that he got sick.
Until finally he decided he needed to eat a healthy breakfast and decided to eat bamboo.
And ever since he was pleased because he liked the bamboo.
