It's true: you really can get more hours and days of play out of a box than out of any toy.
First, it is a fort:
Then it becomes a lighthouse:
After that, it becomes a conquest - how hard must I pull to tear the flaps off?
And then, a ramp for cars.
Finally, it morphs into a slide. I had a video clip of Iain sliding down on bis belly - but I can't find it. Just close your eyes, think of a seal doing tricks, superimpose Iain's cute face on the seal, and you'll have the gist.
