for kai sato:

so, your book are really great but there are some problems. like your story is very simulator and there is only one in the book then it's the end and the next part and it's the same. your story are like that:

the animals are doing something -> and there is a problem -> they found somebody to help/they got an idea how to solve the problem -> they solve the problem -> end of the story.

don't get me wrong, everybody has there own way of making books📚 but I think if you change the problems, it would be better.
