Steps in Digestion

At lunch today, Conor was playing with his black olives--which he loves to eat. But he starting getting a little creative and put them on his fingers, telling us they were puppets. So we named them Oliver and Olivia, and then he ate them.
When I asked where Oliver and Olivia went, he said, "I ate them."
So I said, "But where did they go?"
He answered, "In my mouth."
We have been reading a book about the human body, and learning about the esophagus and stomach and so on, so I asked, "Where did they go next?"
Without any hesitation, he said "To the park!"
