The Enchanted Grotto is a location from the 1985 animated series She-Ra: Princess of Power.
She-Ra: Princess of Power
Hidden on a deserted island, the grotto could only be found if someone led the way. It was large enough to hold a full sized clipper, the Falcon's old ship, while the Falcon himself had a small but comfortable cave to live in.
Falcon grew ill and knew it, but the enchanted air in the grotto served to keep him alive, albeit with the condition that he could never again leave the grotto. It is possible that he enchanted air was also the cause of Davy Jones' ability to speak.
The only way for the Clipper to leave the grotto was through an undersea entrance, which was only revealed if the water in the grotto was lowered by the blowing of a magic shell.
