At one point in development, Pinna Park was meant to function as another hub area. This is evidenced by the fact there are four unused "gate" objects found in the stage's files. These include a ring of manta rays, a shell containing a portal to Noki Bay, and a portal that goes to Pianta Village. The stage also has a MarioPositionObj, which controls where Mario ends up after leaving a course. The only other stage in the game that has gates and MarioPosition objects is Delfino Plaza.
