Scuttle Town is a fishing port town. Shantae is the 'Guardian Genie' (actually only a half-genie) of the town and is responsible for its protection. The town is run by Mayor Scuttlebutt. Mimic lives here when he isn't out adventuring - he is first seen when his workshop is destroyed and then hangs out on a dock during the course of Shantae. By the time of The Pirate's Curse, he owns a new workshop. Scuttle Town has an Arabian architectural style.
In addition to being a town, Scuttle Town is also a level - the first level of Shantae and The Pirate's Curse in fact.
In Risky's Revenge, the deed to the town is given to the Ammo Baron and is renamed Ammo Town, although by the end of the game Mayor Scuttlebutt manages to get the town back. In The Pirate's Curse, however, the Ammo Baron reclaims the town again and fortifies his now legally-owned town into a military fortress. By the end of the game, Shantae uses her genie powers to destroy the entire military additions and, frightened by her powers, Ammo Baron leaves the town with his army in a hurry.
According to Matt Bozon's interview for the Shantae Wiki, Scuttle Town's shoreline is made of two coves: a small one where the town used to be in the past, and a larger one where Scuttle Town sits now. Shantae's Lighthouse is the last remnant from the old town, and from there she has a long view of the town.[1]
