Pip and Posy are having a lovely day at the seaside, collecting shells and digging the sand. But when Posy has a nap, Pip makes friends with a boy called Zac. Zac is very cool: he has lots of fun toys and beach gear, AND he$174s really good at handstands. So, to her dismay, when Posy wakes up, she finds that Pip is more interested in playing with Zac than her.
