I have a 3 year-old son and he has a couple pull toys. One is a wooden dog on wheels and the other is a stuffed safari animal train where the animals can come apart and the wheels unvelcro from the bottom of the feet. He loves both of these and often pulls them around or takes the train apart and plays with the animals individually. As he hates to have anything together the way it was intended, he also loves to take the wheels off and use them for drum sticks, stir sticks, etc! He has found much enjoyment from these toys, sometimes in ways other than the original intent--- to be pulled.
