Whirlpool[conjectural title] is a type of environmental hazard present in Kirby and the Forgotten Land. It appears as a raging spiral current inside a pool of water. When any item or object, including Kirby, gets too close to a whirlpool, that object will start to be dragged by the motion of the current and gradually pulled inward. Once it reaches the center, control is taken away and the object is sucked down into the water. For Kirby or Bandana Waddle Dee, being sucked into a whirlpool has the same effect as falling into a bottomless pit: after a brief moment, they take heavy damage and then are returned to the nearest safe area outside the whirlpool. For enemies, items, and other objects, such as Knock-Knock Nuts, being sucked into the whirlpool effectively removes them from the field of play. Enemies in particular can be seen being "defeated" at the bottom of the vortex.
Whirlpools are first encountered in the stage Abandoned Beach, but are found in many other stages from there. They can come in a wide variety of sizes, and may spin either clockwise or counterclockwise. Some of them will move across the surface of the water. In Fast-Flowing Waterworks in particular, several rooms have pools that are entirely encompassed by a whirlpool. Kirby can fight the current by jumping with regular timing or sidestep them by hovering over them.
- There is at least one example of a whirlpool that does not harm Kirby when he is sucked in, instead taking him to a new area. This whirlpool can be found in Concrete Isles (details on that page).
