Jellyfish Sisters

In the game Mario & Luigi: Superstar Saga, there is a relaxation center in the northeast section of Gwarhar Lagoon. In there, you will meet the Jellyfish Sisters, Gigi and Merri. They give hand massages, and also possess the powers of the Firebrand and Thunderhand. Gigi wears red while Merri wears green.

After Mario and Luigi learned their Firebrand and Thunderhand tricks, the sisters teach them new moves to use with their techniques, such as being able to walk sideways or run quickly.

Trivia

 * The two sisters are similar to Mario & Luigi as one wears red, and the other wears green.
