Hey? There's a caterpillar hanging there.

There is a secret in the body of the cuttlefish.

★A super bestseller in Japan, selling 5.3 million copies!★
★#1 in elementary school student popularity poll for two consecutive years★

“Is there an animal more pitiful than me?”
The more I brag, the more sad the animals become!
A whimsical animal guide that received overwhelming support from children.

A competition that never existed in the world was held.
It was called the 'Unfortunate Animal Showcase'.
In the first event, the 1st Pitiful Animal Showdown, a total of 122 pitiful animals participated, so pitiful that it would be sad to come in second.
Since its publication, the "Poor Animal Showdown" has sold 5.3 million copies in Japan, and is an extremely popular series that has been loved so much that it has been ranked first in elementary school student popularity polls for two years.
As the original that started the craze of 'funny and informative animal guides', it is full of unique fun and informativeness.

A kakapo that can no longer fly because it ate too much, an electric eel with an anus in its neck, and even a ladybug that evolved to be unappetizing.
When you open the book, you will find confessions from animals that are all absurd but somehow heartbreaking.
As you read, giggling and saying, "What kind of animals are these?", before you know it, the characteristics of animals and the mysteries of evolution will come into your head.
In addition, it includes all the basic information necessary for an animal guide, such as size, habitat, characteristics, and English names.


"Showcasing the irony of evolution amidst laughter and admiration!" - Lee Jeong-mo (former director of the National Science Museum in Gwacheon)
It stimulates scientific curiosity and fills the fun of reading.
A book that teaches the joy of learning new knowledge

As you read this book, you will find yourself asking yourself questions like, “Why does that animal look like that?” and “Why does it have such useless abilities?”
The unique appearance and characteristics pique children's curiosity, and scientific explanations follow to satisfy that curiosity.
It also explains, at a level suitable for children, not only the characteristics of each animal, but also what evolution is and how ecological characteristics affect living things.
I am talking about the fact that even appearances and abilities that seem pitiful to the human eye are, when you look closely, each person's own serious strategy for survival.
As former director of the National Science Museum in Gwacheon, Lee Jeong-mo, who supervised this book, said, animals that “go beyond mere rarity and embody the irony of evolution” are not only fun subjects that stimulate children’s interest, but also serve as a good gateway to understanding the natural world.


A story about humorous animals and a cartoon that you can understand just by looking at it.
Even a surprise 'animal theater' appears when you turn the pages of the book.
A book full of things to see that you'll want to keep reaching for!

The 1st Sad Animal Showdown is not simply an encyclopedia listing animal information.
The vivid illustrations and language give readers the pleasure of watching a 'competition' where animals come forward and each show off their skills.
One impressively captured scene of an animal brings laughter, and the accompanying dialogue, along with the warm picture, creates a sense of familiarity.
The 'Whirly Theater' located in the corner of the book is also a hidden fun corner of this book.
A small picture in the lower left corner shows a surprising video with moving animals as you quickly turn the pages.
There are even star ratings that indicate the 'level of regret' and comics that easily explain the evolution that appears here and there.
This is a picture book full of visual pleasure that you won't get tired of looking at again and again.
Funny and bizarre, yet somehow heartwarming, animals will make children's perspectives on nature a little more affectionate and profound.
