Gemstone Dolphins

The Gemstone Dolphins are characters from Barbie: Dolphin Magic. There are four Gemstone Dolphins: Emerald, Topaz, Ruby and Amethyst. They have gemstone markings on their sides.

Story
Isla, a mermaid, was swimming with the Gemstone Dolphins when Emerald was captured. Isla leaves the dolphins to save Emerald. Emerald is put in Marlo's research facility. Isla tries to free Emerald, but Barbie Roberts stops her and convinces her to wait for Hugo, a vet, to come the following afternoon and check if Emerald is healthy.

Marlo tells Hugo to come in the morning instead of the afternoon, and says to Emerald that he is going to make her a lot of money. Isla goes swimming with Barbie in the morning, and the Gemstone Dolphins greet them. Hugo arrives and Skipper discovers that Hugo is not a vet, and he actually owns a sideshow company. The Gemstone Dolphins find Emerald and Ken lets them into the facility, but Marlo orders him to capture them.

After the Gemstone Dolphins are all captured, Isla gets into the pool with them and they all hide. Barbie helps Isla and the Gemstone Dolphins to escape, but Marlo and Hugo pursue them. They successfully get away, and Hugo leaves in his helicopter. Isla and the Gemstone Dolphins part ways with Barbie, but are later reunited.
