Overview

• The expansion reshapes 12 stages into “Starry Stages” after an in‑game meteor event, introducing new routes and hidden collectibles across all six worlds.
• Three new Mouthful Modes debut — slide/sign sledding, gear wall‑climbing, and spring jumping — to drive fresh traversal and puzzle designs.
• Enemy encounters are tougher with added boss health, attacks, and phases, and the Colosseum gains an Ultimate Cup Z EX finale for a steeper endgame.
• Critics describe the add‑on as a concentrated level pack that builds on the base game’s design with tighter platforming and smarter secrets.
• The Switch 2 Edition is available now, with a full package on the platform and a reported $30 upgrade for existing owners; reviewers estimate about 10 hours to 100% the 12 stages and 85 new figures.
