A crippled Fat-Eyed Worm was an abnormally high-quality Fantastic Beast in the eyes of that client.
The Fat-Eyed Worm heard with its own ears that the customer really liked such a strong Fat-Eyed Worm and wanted to buy it as his Fantastic Beast.
The people from the Feeding House naturally wouldn't refuse. Just like that, the Fat-Eyed Worm was bought.
In the beginning, the Fat-Eyed Worm was also looking forward to how this big customer would treat it and whether it would train and grow with him.
However, it and the people of the Feeding House did not expect that the excuse of that big client was fake. It was all fake!
The Fat-Eyed Worm and the other Fantastic Beasts were all locked in the basement. They were locked in a dark iron cage and could not see the sun.
Every day, a Fantastic Beast would be taken away by someone wearing a pure white mask.
