I see what you mean now, Honey, about the other versions. Amazon.com also sells the versions with a white blonde-haired mermaid and red headed mermaid whose "hair is too fluffy".
One of the 5* reviews (89%) of the book with the black mermaid on the cover:
5.0 out of 5 stars Get a grip people!!! These are WONDERFUL books!
I own the previous That’s Not My Mermaid book which features a white mermaid on the cover. I actually looked to order it again as an adoption day gift for some close friends. It would NEVER EVER cross my mind to consider the book racist because a white mermaid—or any color mermaid for that matter—had hair that was too fluffy. Good grief! These are WONDERFUL books and I feel sorry for the children that miss out on them because of their PC induced psychosis suffering parents. Where does the insanity end???!!!
There's a whole range of "That's not my …" books, including the following:
That's not my unicorn, its mane is too fluffy
That's not my bunny, its tail is too fluffy
That's not my hedgehog, its ears are too fluffy
That's not my hamster, its ears are too fluffy
And other books with creatures/things that are too tufty, soft, bumpy or fuzzy.
I want the whole range now!
