Arena Town is a resort town and the home of the Half-Genie Festival, where Half-Genies show off their magic to a live audience. For this reason, it is popular among tourists. It is implied that this is where both Harmony and Plink live.
Tree Town is the hidden island village located on the west side of Paradise Island. It is protected by the resident Half-Genie Vera, who is also the chief's daughter. Tree Town features a dance parlor, where Shantae can participate to earn gems.
Armor Town, located on the east side, is famous for making armor. This town is lead by the Armor Baron, who is the brother of the Ammo Baron of Sequin Land. Zapple appears to be the Guardian Genie of this town.
The Sunken City lies underneath the surface of Paradise Island. It is primarily inhabited by monsters, but is also the home of the mysterious Seven Sirens. When the other Half-Genies disappear during the Half-Genie Festival (which is implied by the announcer that they're on break, much to the dismay of the audience), Shantae must explore the city's many labyrinths to find them with a bit of help from Mimic.
