I wish I got this for my son long ago! It has little push buttons on each bumper that makes it go forwards and back everytime one is touched. You don't necessarily need the track with this toy, he has a great time on the wood floors without it.
I got this for my son for his second birthday. It's his "bubblicious bubble drill". What a simple design for hours (if I let him) of fun. Simply pour some bubble bath into a hole(it only holds about a teaspoon, more than enough to make a load of bubbles) and it seeps down the rod onto the bubble bit.
