Which game is described as the only Kirby game for the GameCube?

Kirby Air Ride is described as the only Kirby game released for the Nintendo GameCube.

Developed by HAL Laboratory and published by Nintendo, Kirby Air Ride arrived in 2003 as a racing spin-off. Players control Kirby or differently colored versions of him while riding air vehicles through races, arenas, and objective-based challenges. Its controls are unusually simple: steering and many actions are handled with a small number of inputs, emphasizing speed and accessible multiplayer competition.

The game contains three major modes: Air Ride, which features conventional races; Top Ride, viewed from above; and City Trial, an exploratory mode where players collect upgrades before a final event. Up to four players can compete locally, and the game was notable as the first GameCube title to support LAN play using broadband adapters and multiple consoles.

The wording can cause confusion because several Kirby games appeared on nearby Nintendo systems, including Kirby: Canvas Curse on Nintendo DS and Kirby Tilt 'n' Tumble on Game Boy Color. Kirby Air Ride, however, was the series' sole released GameCube title. It also had a long development history, beginning as an early Nintendo 64 project before being reworked and completed for GameCube.
