Highly suggest an electric screwdriver.  My daughter and I put this together with both children sitting on it.  When I got it outside, their attention was immediate and held for a conciderable length of time.  The four year old left for a bit to ride her bike, but came back.  The two year old was completely engrossed.  We couldn't pry him away.  He got so cold he was shivering and we could still barely coax him in the house to get warm.  It was fun to watch.  I wouldn't use this product inside though.  The two year old figured out right away how to open up the drain for the water.  He opened it up and crawled under it.  lol!  Too funny.  I wouldn't worry about it not coming with an over abundance of toys.  The kids have their own ideas.  These two took sea shells I had collected in FLA and played with those.
