This wiggles musical big red car is a fun toy, but there really isn't much for the child to do. I will say though it is very entertaining for younger kids to watch and chase after. This car has an on/off switch and what you do is press down on the wiggles characters to start the song "big red car" and then the wheels roll forward and the wiggles pop up and down.
My biggest issue with this is that it doesn't always work super well. It seems that if you have a good one then there isn't much of a problem, but often times either the wiggles won't go up and down or the car doesn't go forward nicely. It also will really only go well on concrete, wood or linoleum, something flat. Ours will not move at all on carpet, which is somewhat expected but if I am letting a young child play with it then I prefer to have it on a soft surface.
The song is catchy and cute atleast and it usually lasts long enough where it ends up running into something before it is over. It is a toy though that was enjoyed, more so by the younger kids, at about age 1 or 2. Interest was lost quickly in it.
