I feel like the scientists in the movie Jurassic Park, when they learned that the velociraptors could open doors.  Yes, Mae loves this stool.  She spends abundant time climbing up, down, around, and through it. Accordingly, I usually leave it against a blank wall.

Yesterday, she managed to move the stool to a much more exciting location.  Fortunately, I found her in time, but who knows what tomorrow will bring.
