We already had one of these then a year later received another. Our kids ended up opening the second one and played with it for about an hour inside - then the big bad parents that we are put it away. They love this set especially in the winter to create a world of adventure inside. The tunnel has many uses as our kids have opened our world to this - "tunnel monster" is the most memorable. Also this set is a great addition to any obstacle course. http://www.google.com/products/catalog?client=safari&rls=en&q=discovery+kids+tent+and+tunnel&oe=UTF-8&um=1&ie=UTF-8&tbm=shop&cid=15373881202968514808&sa=X&ei=Yi1_TrrQD-Tg0QHvxNQC&ved=0CE0Q8wIwAA#ps-sellers
