A Reading Corner Mystery!

Whaaaa??! I've finally (almost) finished E's room! We've had quite a fun time creating a little cozy space for her. I sleep in there with her at night and decided to make my bed into more of a day bed for a cute little reading corner. Then this morning, just when I least expected it:

A Reading Corner mystery! E and I keep a journal handy in our corner to write about books, the weather, and anything else! I recently decorated the cover and added a note: "Guest Writers Welcome". This morning I woke up to find this little note written under one of my entries: "What a fandingle! This little miss jingle! Cute as a button, but lighter than mutton! -Mr. McJinglepots." E and I are quite confused by this... Will write more later.
