Everyone knows that at the zoo, the kids like watching the elephants... "Do their business". Well, what if Dinosaurs pooped? It could be used to eventually get rid of some minor injuries, like Swallowed Phone and Swallowed Object, and maybe Bracken Poisoning. And there's Precedent, as Dinosaur Poop as been a plot point at least twice in the Jurassic Franchise, First with the Triceratops in JP, and then the Spinosaurus and the Satellite Phone in JP3. Not saying it needs to be anything more than a particle effect, either.
