A boy and his grandad set off on a scorching adventure! It's the hottest day of the year, hotter than broccoli soup, hotter than the Atacama Desert, hotter than the surface of the sun. It's just the right kind of day for a boy and his grandad to go for a picnic. But as the sun beats down, Grandad keeps having to stop for a rest, and by the time they find the perfect picnic spot, some pirates have beaten them to it. Good job they have enough food to share...
