He is a sunfish that is best suited for water levels.
Role in the series
In Kirby's Dream Land 2 and 3 he appears as an Animal Friend.
In The Crystal Shards when the player mixes the Stone and Cutter abilities, Kirby gains the mix ability Stone Friends, which lets him turn into statues of any of his past animal friends, including Kine. However, the Kine statue is useless, as it can only turn around. It will not even move (besides turning around) in or under water. This is reminiscent of the Stone ability in many Kirby games, like Kirby's Return to Dream Land.
In Canvas Curse, he appears as one of Paint Roller's drawings.
In Kirby Mass Attack's Kirby Brawlball sub-game, Kine rests at the bottom of the pinball machine. He saves Kirby from falling into the sink once before disappearing, and he comes back if Kirby activates all the switches along the top of the machine. Kine also appears in the Kirby Quest sub-game along with the other two original Animal Friends if Kirby loses a battle.
In Kirby Battle Royale, he appears in the audience in the Slam Hockey game.
In Team Kirby Clash Deluxe, in the main hub, he is seen sleeping on the bench after the player defeats Landia EX.
In Star Allies, he appears alongside Rick and Coo as playable Dream Friends.
