Port Prisma

Port Prisma is at the center of Prism Island and serves as the main area in Paper Mario: Color Splash. It is split up into four districts: the blue district, the red district, the yellow district, and the harbor district. At the start of his journey, Mario arrives by boat in the harbor district.

In the square of Port Prisma is the Prisma Fountain, drained of all its color which is being carried by the Big Paint Stars that Mario must retrieve in order to restore these colors.

Trivia

 * Port Prisma somewhat bears a resemblance in layout to Rogueport, with a staircase in the harbor leading to the main square where the major collectibles of the game are put in place.
