The colors are very cheerful. The tunnel is long enough to be fun. I positioned on a fairly thick carpet to preserve the gentle lap of children and allow them to freely chosen and meaning antics. The tunnel comes in a large cardboard box to the delight of children. I added a room to child multi-cardboard castle. A support more to exercise the artistic talent of the family. Drawings, carvings, paintings ... Finally the tunnel fold for easy storage But be careful to child size. From 3 years but not too big either. the passages are narrow
