It's cute fabric and could be for both a boy or a girl. If you're not really feeling this fabric, look at the northcott stonehenge undersea. No pinks or purples, but lots of orange, green and yellow colors just like your turtles.
They also have a cute whimsical dino roar fabric with carton dinos and it does have purple in it. Dinos can be both boy or a girl, but to me just scream, boy.
