Making Squash from Watermelons

I noticed my "watermelon" plants were not viney.  I thought maybe I go some type of hybrid, well, really hoping that is the case.  I began researching and comparing pictures.  I have learned that I was sold the wrong seeds at the feed store. 

WWWWWAAAAAHHHHH! WWWWWAAAAHHHH!!!  :(

The seeds turned out to be squash seeds and now I have two beautiful non-watermelon squash plants. I bought the seeds at our local feed store and the seeds were coated in a blue coating which is some chemical that encourages germination.  I did not question the seeds, I mean, why would I?  The seeds had the same shape and size as the watermelon seeds.

Dammit.

Here are the pictures of my squash plants.

So now, I am going to go to Home Depot and purchase some watermelon seeds.  It may be a bit late to plant them but by George I am going to plant those babies!

I am wondering how many other people in Cooke county are growing squash instead of watermelon...
