After Shell got the earring he gave a delighted squeal, and then nothing will be done for except that the second dolphin must have one as well. After Gwen gives Coral the Turquoise, her hand is bumped in thanks, and both now are diving and jumping, squealing and wheeling, dancing through the water on their tail fins in joy! It's glamour, as pure and simple and lovely as any child's laughter, and refreshes the fae on the boat with a joyful feeling that helps wash away worries.
