Where is Hattie

One afternoon, after a full day of play, I called Hattie to come upstairs for a snack. Normally she is the first one there since she spends a large part of her day asking for snacks. She wasn't coming and I had called a whole bunch, so I decided to go look for her and see if she had fallen asleep. I did a quick check in her room- nothing, Tanner's room- nothing, couch area- nothing. That was weird, I thought. So I decided to check her room better. I went in there and heard a really weird, muffled snoring sound. Still couldn't see her anywhere. Then I figured she was under the toy box. (at this point I ran to grab the video camera)
I lifted the box off, and there was Hattie, sound asleep in a little sweaty ball. I'm not sure what possessed her to stay under the box long enough to fall asleep, but then again, I'm never quite sure what goes on in her head. She slept for a long time after too and came upstairs happy and ready to play some more (after her snack of course)
