1st Duel [Text, Anonymous]

[The anonymous post goes up in the evening. Anthy had been debating saying anything at all - still incredibly unsure of the reasons why she was brought here and by who, putting out any sort of message was a risk, and she'd been strongly advised to wait a while before making any posts. But at the same time, her curiosity had been getting the better of her. Just what sort of people found themselves living in this place? Could it be anyone she knows? Could it be...her?

She's decided to risk it. After all, today had already resulted in some eventful happenings that she could use to start a conversation, as well as get a better perspective on life in this world.]

Would someone be able to explain something to me?
Today, I saw someone called a "Pokemon Breeder" selling small brown creatures as pets, and charging quite a lot of money for them.
However, he kept saying how they "weren't right" for him, and that he was trying to "get them off his hands". Do people often speak about Pokemon like this?
I am new here, so I wouldn't know for sure, but it seemed wrong to me.
If these Pokemon are all supposed to be so powerful, would little cosmetic things really make them unwanted by someone?
