Wandering Shelter

We spotted the islet when the sun was at its highest point of the day, and for all of us it was just an islet.
Except for one unusual fact: it was moving!
As we got closer we realized that it wasn't an island, it was a huge turtle, covered in vegetation.
But the surprises weren't over: we realized that a person lived on that animal, a person who was greeting us and inviting us to come closer.
It was one of the strangest encounters of my life.
