Dolphin is a form that both Kirby and Prince Fluff can take on in Kirby's Epic Yarn. The two can transform into this form by getting the relevant Metamortex. It first appears in Blub-Blub Ocean, then later appears in Deep-Dive Deep, Fossil Reef, and Meta Melon Isle. It is the most common Metamortex transformation in the game.
Kirby becomes a pink dolphin with red fins, a blue tail fin, and a purple dome. Prince Fluff becomes a blue dolphin with orange fins, a blue tail fin, and a purple dome.
While in this form, Kirby and Prince Fluff have much more speed and maneuverability underwater than in their regular Submarine form. By pressing the 1 button, they can perform a powerful surge attack that will break all blocks and destroy every kind of enemy except the giant Danglerfish and Amprey. When holding down the 2 button when near a ball, the two can balance it on their nose and throw it into the air. Kirby and the Prince can jump great distances out of the water and swim against the current to the extent of being able to climb up waterfalls while in Dolphin form. If Kirby somehow ends up on land, he will slide in the direction he is currently traveling in until he enters water again.
- This is the only Metamortex transformation made for underwater purposes.
