Reviews
Overall this was a good book for your student or child to have something to do that doesn't involve screens. It is thought provoking and the mysteries get harder as you progress. In the beginning, the book explained the rules of how to solve the puzzles and then it gave you a practice mystery to solve. Your child or student may need you to show them how it works so they know how it works. I went through the steps with my 11 year old and she was more interested to continue to solve more of the puzzles. Make sure they have paper nearby so they can do the puzzles without getting confused and feeling defeated.
Moon Pearl Aquarium is a fun and engaging mystery that gets kids thinking like detectives. With tons of suspects, clever clues, and a mystery to solve, it's a great choice for curious young readers who enjoy puzzles and problem-solving. A fun way to make reading feel like an adventure!
I got this book for my kids, and they really enjoyed it! They loved trying to figure out the clues and guessing who the thief was. It kept them interested and gave them something fun to work through together. A great choice for kids who enjoy mysteries and detective stories!
This book is such a fun puzzle book! I love logic puzzles and this was a way to introduce them to my kiddos. It would have 5 stars, but my kids said 'that's ai!' and were very disappointed. They much prefer actual animation or even none at all.
I enjoyed trying to figure out who stole the Moon Pearl from the aquarium. Daisy has 10 suspects to investigate, and I liked following the clues and trying to guess the thief before she did. It was a fun mystery without being too hard to follow.
