Stand and Spin?

Toddler Tales:  Cam is almost 29 months old now.  He is running all over the place getting into everything.  We've been getting him toys that help him burn off his energy, like one of these... (I had one of these when I was a kid, but I thought you were supposed to sit in it...)

Cam just effortlessly climbs up on it.  (with nothing to hold onto to help him up.)  And even scarier is that he will carry this around the house to climb onto higher areas.  (Even though it is bulky and a little heavy.)  I guess you have to admire his resourcefulness...
