Water is introduced to the games in Kirby's Return to Dream Land, where it is first revealed in the game's teaser in Nintendo's quarterly investor report video, then later in the games' E3 2011 trailer where Water Kirby is seen battling a boss. Water Kirby's appearance in Kirby's Return to Dream Land looks different to his appearance in the anime, and he cannot simply inhale seawater to get it like he did in the anime. He has a hat similar to Tornado's, but is made of a vortex of water which can be projected to wash enemies away.
Kirby shoots a pulse of water. It follows the terrain surface regardless of whether it goes uphill or not until it moves off-screen. The water moves at the same speed as Kirby's Surf.
A special dash move. Kirby surfs on a wave. This move allows Kirby to travel over the surface of a body of water or a fiery platform.
16 (when Kirby turns around)
Surf + Button 1
Raises Kirby's surf wave and deals damage for several seconds. Kirby is invulnerable during the attack.
↑ + Button 1
Projects a column of water straight up, but Kirby cannot move while doing so. Pressing button 1 repeatedly maintains the column. If executed in mid-air, Kirby carries on moving in his original direction.
16 per hit
(midair) ↓ + Button 1
Kirby hovers by spitting water towards the ground. Hovers as long as Button 1 is depressed. After the hover starts, directional keys control Kirby's movement and hover distance.
8 per hit
↓ + Button 1
Splashes water at Kirby's feet, dealing damage to anything close to him. Has short range.
16, 14 (rapid subsequent uses)
Hold ↓ then ↑ + Button 1
Kirby crouches, then projects a sphere of water around him and ends with a rainbow flourish. Has longer range than Water Crown. This move has difficult execution timing - the player needs to press ↑ before Button 1 or Kirby performs Water Crown instead, and Button 1 must follow suit a split second after ↑ or Kirby stands up and does nothing.
In the anime, Water Kirby's body changes to what looks like a translucent blue gel, with a golden crown containing a cresting wave on his head. Naturally, Water Kirby attacks by spitting geysers of water to blast the enemy away.
