Gwarhar Lagoon

Gwarhar Lagoon is a rocky, tropical resort area in the southeastern part of the Beanbean Kingdom. The Mario Bros. travel here to find a piece of the Beanstar during the events of Mario & Luigi: Superstar Saga. The Beanstar piece is found on the top of Hermie III's shell and the Bros. must battle him for it. Spangle becomes the Beanstar's replacement.

Also, the Jellyfish Sisters run their massage parlor in Gwarhar Lagoon and teach the Bros. two new hand techniques; Fire Bros. and Thunder Bros.
