Which creatures can reveal, but only to someone clever enough to catch them — the location of buried treasure or gold hidden at the end of the rainbow?

According to Irish folklore, these solitary, green-clad fairies are the key to finding a hidden fortune. Originally described as shoemakers to the other magical folk, they are said to have accumulated vast riches over time, which they guard with extreme jealousy. The core of the legend is that if a human manages to catch one, the creature is magically obligated to reveal the location of its hidden pot of gold in exchange for its freedom.

The famous idea of the treasure being hidden at the end of a rainbow is a more modern addition to the myth, but it perfectly suits the creature's tricky nature. Since the end of a rainbow is an optical illusion that can never be reached, it’s a clever way to promise a treasure that can never be claimed. This highlights the second part of the challenge: you must not only be quick enough to catch one, but also clever enough to outwit it.

Even after being captured, these little men will use every trick and riddle they know to deceive their captor. They might try to distract a person by pointing out something behind them or creating a sudden noise. The moment the human's gaze is broken, even for a split second, the fairy will vanish, taking the secret of its treasure along with it.
