A House

Pooka: Mama, House! (Turning a book on its side with the pages opened)
Me: Oh? Did you make a house? Who lives in the house?
Pooka, getting on her belly to look inside to see who does live in her house: SHOES!
Me: Shoes?
Pooka: Daddy's shoes!

Then of course she ran to get Daddy's shoes and tried to walk all over the house in them. :)
