Dino Deodorant

Today I was reading a book with Logan. Right now, just about every book we read is about dinosaurs and this one was about Allosaurus. We were alternating reading each page - He'd read one and then I would. There was a picture of an Allosaurus about to attack some Brachiosaurus on the page I was reading. The Brachiosaurus was red with some white down its neck and the front of its body. Logan stopped me and said, "Is that Brachiosaurus all bloody?" I said that it wasn't, it just had red skin. Then, he pointed to the white on him and said, "Oh and that is its odorant?" It took me a few seconds to put together what he was trying to say, but I finally got that he was talking about deodorant! I was laughing at this and he said, "I think the Paleontologists must have snuck in and painted some deodorant on his skin." Where does he come up with this stuff?
