Oh Toot Toot, send me a letter!

Here are Fiona and Nora, enraptured by the letter sent by Toot Toot. Each child took their own letter up and put it away in their nightstand afterwards; but Nora first wrote a letter back to G and TT on the back. When she read it to us, it purportedly said, "Dear Grandma and Toot Toot, I truly hope you enjoy your audiobooks." Where, exactly, does she get this stuff?
