Good find Inspector Clouseau.
Square Watermelons
A round watermelon can take up a lot of room in a refrigerator and the usually round fruit often sits awkwardly on refrigerator shelves.
Smart Japanese Farmers have forced their watermelons to grow into a square shape by inserting the melons into square, tempered glass cases while the fruit is still growing on the vine.
Yep, square watermelons grown in square wooden crates for the limited space Japanese refrigerators.
