It took me a while to figure out... she must have goodies buried back there. And... as luck would have it, our current Baby doll went MIA about a week before the tree came down.
For those of you unfamiliar with Baby... When Miss Lou is being particularly stingy with her loving, I start yelling for "Baby." I tell Baby ( the stuffie du jour) all about how mean Mabel is and how Mabel won't kiss me and Mabel won't cuddle me and Mabel won't let me rub her tums. I will kiss and hug and cuddle and rub Baby's tum. But eventually, I push it too far and ask Baby if she wants to go to the creek and leave Mabel at home... and shortly thereafter, Baby either dies a tragic death or "disappears." (I feel like I'm living with a Mafioso sometimes!) Here's a link to the rather funny beginning of the Baby Game!
Anyway, I'm pretty sure Baby is buried around the stump of that tree based on the way the girl is acting. Time to up the ante and find a shovel!
