Willow the Wombat is bored. Bored, bored, bored. It's raining and he can't go outside to play. Down in the cellar, Willow finds an old chest, full of interesting things: flying overalls, a compass, goggles, caps, maps and an old, woolly scarf . . . All things that had once belonged to his grandpa. And in amongst it all is Grandpa's journal.
As Willow sits down to read the journal, a magical thing happens. All of a sudden, Willow finds himself reliving Grandpa's great adventures! One minute he is zooming around in the sky in an old timber plane; the next he is an explorer . . .
