He poops gems? Needs more fiber in his diet.
He can't do diet anymore because he's already ....
Well, his story is rather tragic...
His wife wanted to get all the gems from him at one single go.
So, one day she thought hard and at last clicked upon a plan.
She decided to kill him and get all the gems together.
But after she did that, there was nothing but blood all around & no trace of any gems at all.
She was highly grieved because now she would not get even one single gem.
This is also why we never get Columns IV.
He's already gone, because of his greedy wife.
