Lambikin
Retold for young children from Indian Fairy Tales (ed. Joseph Jacobs, 1892), public domain.
A little lamb named Lambikin set off one morning to visit his grandmother, trotting happily down the road and singing to himself as he went. Along the way, a jackal spotted him and thought he looked like a fine little snack. "Lambikin, Lambikin, I'll eat you!" the jackal called.
But quick-thinking Lambikin called back, "Not yet! I'm off to my grandmother's house to get nice and fat first — you can eat me on my way home instead!" The jackal, who liked the idea of a fatter meal later, let him trot on by.
The very same thing happened with a wolf, and then a tiger — each one stopped Lambikin, and each time he sang out the same clever answer, and each time he was let go on his way. At his grandmother's house, Lambikin ate well and grew round and happy, and his grandmother, worried about the journey home, tucked him inside a big, sturdy drum and sent him rolling home inside it instead of walking.
As the drum went bumping down the road, the jackal, the wolf, and the tiger each heard the strange, hollow booming sound and asked, "What's making that noise?" And Lambikin, tucked safe inside, sang out, "It's only Lambikin's drum, going bumpetty-bump all the way home!" — and every one of them let the mysterious drum roll right on by, never guessing their dinner was hiding inside it all along.
Talk about it (ours, not from the source): Lambikin used a clever trick — twice! — to stay safe. What's a clever plan you'd use to solve a tricky problem?

Why public domain: US: first published 1892, more than 95 years ago, so public domain in the US. Editor Joseph Jacobs died 1916; India's copyright term (life + 60 years) means the compilation has also been public domain in India since 1977.
