The elephant carried them through the jungle until they came to a river.

Then he set them down on the ground, said goodbye, and went off back into the jungle.

"How are we going to cross the river?" Jack asked Mr. Daydream.

"Perhaps I can be of assistance," wheezed a particularly oily voice coming from the river.

They looked, and there was a crocodile.

"Use my back as a bridge," suggested the crocodile.

It was very helpful!
