Jellyfish Sisters

The Jellyfish Sisters, Gigi and Merri are the owners of a relaxation center of Gwarhar Lagoon in Mario & Luigi: Superstar Saga. When Mario & Luigi arrive at their relaxation center, the Jellyfish Sisters give them hand massages, and possess the powers of the Firebrand and Thunderhand. Gigi wears red while Merri wears green.

After Mario and Luigi learned their Firebrand and Thunderhand ability, 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.
