The listings show both physical and digital releases — for example, physical cartridges and digital downloads.
Several descriptions highlight 'Mouthful Mode,' where Kirby inhales large real‑world objects and temporarily transforms, gaining new abilities tied to those objects.
Multiplayer options vary: many entries list local multiplayer, several list both local and online multiplayer, and some feature drop‑in/drop‑out cooperative play that supports up to four players.
Some platforming entries support drop‑in/drop‑out local co‑op with Kirby plus up to three additional players — up to four players total.
Next‑generation editions are described as offering higher resolution and faster frame rates; a few listings also note additional story content included for those editions.
Listings mention several progression systems and collectibles: rescuing characters to expand a home base (unlocking shops, leaderboards, and ability upgrades), decorative items for the player home, strawberries and a Gourmet Rank that unlocks customizations, redeemable Present Codes or compatible accessories for items, and a Gotcha Machine location for finding collectibles.
Several listings include online multiplayer and state that an online membership and account are required for online features; availability varies by country and an internet connection is required.
