You head north to a dead-end, but a pleasant and sandy one. The beach is beautiful and the weather is fine, so you splash around in the sea for a bit, before spending a couple of hours drying off in the sun, pretending to yourself that you're hardworking and in the middle of doing an essay. After a while of slumber, you busy yourself with constructing a castle and a dam, both masterful pieces of engineering, after which you feel you deserve another sleep for as long as your skin can survive in the sun.
Hairy doesn't seem to want to join in with the excavations, or even the sunbathing - he just swims around happily in the sea, which is where you leave him a bit later on, when, a little more relaxed, and a little browner, you feel it is time to return to the road and tour some more.
