Danny McGee goes to the seaside with his sister. So far, so normal. But when he sees the sparkling blue sea, he makes a bet with his sister: I bet I can drink the sea, he says.
And he does. He drinks it all up through a straw.
And then he eats a tree, and then he eats a cat drinking some tea, and then he eats a man learning to ski . . .
And so it goes on, until the only thing that is left on the planet is Danny McGee and his little sister . . .
