This kit comes in colourful pieces which slot together to make a track which is stuck to the side of the bath with suction pads. It has balls and "beans" to roll down the track.. It says it's for 18 months plus but my older great nephews enjoyed playing with it for some time. Obviously it needs to be made up for an 18 month old as they are unlikely to be able to slot the pieces together. I can see that it is going to be a bath time favourite for some time.
