Ava's Interpretation of the Farm Animal book

We were all sitting in Ava's room last night looking at and reading books. Ava has a Touch and Feel Farm Animal book which she loves since we have been at the horse barn so much. We were going through the book asking her to tell us the name of the animal and what that particular animal says. She was doing great naming everything and telling us the sound it makes. And then we turned the page to see the Lamb's. Imagine holding open the book and looking at a two page spread with Lambs standing around and a couple of them are standing around a long cut down tree trunk. We asked Ava what the animal was and what it said in which she answered perfectly. Then she points to the tree and says "Poo Poo." What do you say when you can't stop laughing? She innocently pointed again to the tree and says "Poo Poo" which luckily we had enough composure at this time to say "that's a tree." She said, "ohh tree."

I guess since she has been going potty alot lately she just named what she thought it looked like.
