The basic structure of the stage is simple with a long main platform and two thin platforms that mirror each other close to the stage's ledges.
The main gimmick of the stage is that N's Castle rises in the background changing the stage. As it rises, two bridges form and attach to the stage's sides. Getting hit by these will do a fair bit of damage and knockback. The two bridges act as walkoffs but, if nothing happens to them, they will retract, carrying everyone on them to the blast zone.
