Cucumber - Watermelon - ????

Ok, I have grown cucumber before which is why when what I thought were cucumber seeds came up I assumed they were cucumbers. They had the prickly stems and the leaves looked good enough to be right. The fruit even looked the same when it was really small.

Then there came the shape and texture of the fruit as it got bigger... They were smooth and round and began to show long stripes. A watermelon, right?

Nope... I got up this morning and checked on the progress. I figured with all the rain a watermelon would have gotten to the point I would have to do something about it again. When I looked at it there was a strange grey weaving pattern all around the round fruit. It will soon turn a little orange in the middle and be really sweet, I hope. That is what cantaloupe does after all...
