Currents, also known as Water Currents, are obstacles in Kirby's Epic Yarn and Kirby's Return to Dream Land. They are found in watery levels. Currents are often easy to spot by their different coloring and rather vertical line appearance, as shown in the picture to the right. In this picture to the right, this current is dark blue and is a vertical line. Currents appear in a few levels in Water Land such as Blub-Blub Ocean (Kirby's Epic Yarn) and a few stages in Onion Ocean (Kirby's Return to Dream Land). When Kirby (or Prince Fluff, Meta Knight, King Dedede or Bandana Waddle Dee) enters a Current, it will carry them swiftly on its own in the direction it is heading. In the picture to the right, this Current is pulling Kirby down to the bottom of the ocean in a stage in Onion Ocean. Since Currents pull the heroes so quickly, it is near impossible to swim against them. However, in Kirby's Epic Yarn, the player can use the Dolphin's surge attack to swim against currents. Currents can be hazardous since they can put the heroes to touch other enemies or obstacles (such as Spikes) and take damage.
