My Son Can’t Get Enough of Who Would Win
Format: Hardcover
My four-year-old son is absolutely obsessed with the Who Would Win series! We really enjoy the interesting facts sprinkled throughout the chapters - it makes reading together both fun and educational. Since discovering these books, we’ve happily added more titles to our Who Would Win collection. Highly recommend for curious young readers!

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.

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.
