I think this is a pretty good representation of rams in pastry form. I can see the phallic resemblance, but honestly, I think this isn’t bad at all. If you wanted to be sure they wouldn’t be confused with anything other than a ram, perhaps you could get some food-grade paints and paint in eyes, nose, mouth, nostrils, etc. I think the faces being painted/frosted on would help eliminate the tendency to see a dick and make it less ambiguous.
Those fabrics are made of plastic, which is derived from oil, which forms over long periods of time from buried decaying plant and animal matter. 70% of the Earth’s oil is from the Mesozoic Era, which encompassed the Triassic, Jurassic, and Cretaceous Periods, so formed during a time when dinosaurs lived and jokes about oil being made of dinosaurs are common. Oil is actually made of plankton rather than dinosaurs, though.
