Or you can get some fabric paints & add your own...snakes aren't very complicated to draw.
I have a large carry-all for my gear that I take to the pool...I got some fabric paint and added a happy green water snake to the front of the black bag, lol.
(btw, I couldn't find a pic of the L.B. purse that I have for "everyday use"- but it's far less obvious, not her usual bright colors, more coppers/browns on
beige, with lizards & all kinds of animals, not just snakes.)
