Wow! I want one! Ofcourse a watermelon cooler is an absolute necessity! Everyone knows a chilled watermelon tastes better. This is one of those random gadgets that you know you can do without but you would rather get just because it exists. This would be an impulse buy for me. Available for purchase only in Japan though. It has wheels and a handle so your watermelon can stay fresh and cool even when you are on the go.
