That's what it is... his turbo switch is on!!

Taking a moment to watch Thomas the Train.
  I've been practicing with my camera... This picture was actually shot in very low light. I tried a high ISO and a large aperature with an higher shutter speed. 

Well everything makes so much sense now.... the boundless energy, the non-stop playing, the screaming and running and jumping, the making mommy chase him all over the place... His turbo switch has been on all this time!
