Great books, but the Rumble book is the best!
Format: Hardcover, Format: Hardcover
These books are great books and are filled with tons of mammal, animal, and insect facts. However, after buying several, I realized I was buying the wrong books. This is because we wanted the bracket based “who would win” books. They are the best ones! Apparently, the bracket-based books have “rumble” in the title. The pictures will show the difference. There are only two rumble books, 1 of which will be released Oct 7th.

Love these easy to read books.
Format: Hardcover
My kid is obsessed with these books. He will read these books so much that they wear out and I have to replace them. This is a great series of books for young readers. It's great for kids who also like would you rather. There are several books in this series and they are all worth buying.
