Puerto Rico has been known for a long time , as the island of enchantment. There are many reasons why but one of them is the national mascot, simply a small tree frog but this tree fron is very important to the people.
The enchantment is probably the sound it produces.
You hear him at night and specially when it rains.
The people fall asleep with this continuous sound.
If you want to visit, you will here the COQUI, sooner or later.
Who knows , you might even fall asleep to the enchanting sound.
