In Japan they have square watermelons

Watermelons are popular gifts in Japan. They also use them for a game where they have to smash them blindfolded. But it’s an expensive game because square watermelons aren’t cheap (they generally cost in the range of $100 to $160, but maybe that’s not too much for a country with the third largest economy in the world).

The curve-averse watermelons were first developed for ease of transport and fit in the fridge more easily but they have since become a popular novelty product.

Triangular and even heart-shaped melons are not uncommon either. The melons are grown in shaped containers and are very hard to grow (hence the price).

That triangular watermelon is apparently being sold at some $600
