The stage consists of many platforms floating in front of New Pork City. The platforms seem to be random in terms of design and how they are positioned, with very few having any connection to Mother 3 at all. Of particular note, there is a swinging carousel that acts as a platform; and a destructible platform near the bottom of the stage. A floating limousine may also travel beneath the stage; which acts as a temporary platform.
The main hazard of the New Pork City stage is the Ultimate Chimera enemy. During battle, the Ultimate Chimera may randomly spawn in one of several places, and slowly walk around. For a short time, he will patrol a single platform. If a fighter dares to draw near him, he will bare his fangs and chomp the fighter to deal massive knockback and damage; likely resulting in a KO unless positioned so the blow causes the fighter to bounce against another platform and to safety.
