Every year on August 3rd it is National Watermelon day. So, I thought that it would be fitting to tell you some juicy facts about watermelons and also share a few fun books.
Do you know, that in Japan they grow square watermelons? Why? Round watermelons take up a lot of room in a refrigerator and they are also more difficult to cut into slices. Seems like a very logical and creative solution. That being said, MSN news recently reported the that square watermelon sold for $856 . What??? I think that I'll stick with the round ones for now.
However, it might be fun to join the World Championship Seed Spitting Contest held in Luling, Texas every June.
There's also a watermelon eating contest and a contest for the largest black diamond watermelon. Now, that might be some Texas fun that you could chomp into!
"Champion Watermelon award is given to the largest Black Diamond watermelon grown according to the grower's association rules. The top entries in the Melon Contest are sold at auction. The Champion melon has brought between $400 and $22,500. Part of the proceeds from the auction support student scholarships." 
The Watermelon Seed Greg Pizzoli.
With perfect comic pacing, Greg Pizzoli introduces us to one funny crocodile who has one big fear: swallowing a watermelon seed. What will he do when his greatest fear is realized? Will vines sprout out his ears? Will his skin turn pink? This crocodile has a wild imagination that kids will love. With bold color and beautiful sense of design, Greg Pizzoli's picture book debut takes this familiar childhood worry and gives us a true gem in the vein of I Want My Hat Back and Not a Box. 
One Watermelon Seed Celia Barker Lottridge
One Watermelon Seed is presented in a new edition with a bold new cover and interior art. In this deceptively simple counting book, Max and Josephine tend their garden while readers follow along, counting from one to ten as the garden is planted. Then readers can count in groups of tens as the garden is harvested, while they search through the pictures for the many small animals that are hiding throughout. A concise and clever text introduces color and rhythm, and the illustrations are bright and engaging, making this a perfect counting book for children aged four to seven.
