Kuru Kuru Kururin is a Game Boy Advance video game launched in 2001 by Eighting and Nintendo during the system's launch in Europe and Japan. The game was never released in North America. It's an unordinary game that Nintendo officially classifies as a puzzle title. The name originates from the Japanese word "kuru kuru", an onomatopoeia in Japan that is meant to replicate the sound of spinning, while the name Kururin is named after a popular carnival game in Japan.
In Kuru Kuru Kururin, the player character is a duck. The titular Kururin is the aviator of a Helirin. The Helirin is an elongated stick like object that is constantly rotating, whereas in previous similar games (such as a Playstation 1 game called Irritating Stick in America) the stick was still. Though the Helirin is constantly in motion, the player has control over where it goes. The goal is to maneuver around walls and objects. In order to do this, you'll have to move your Helirin when it's in a certain position. For example, if you're attempting to go straight down, though the walls are two tight for you to go through if the Helirin was horizontal, the player is able to wait until the ship is straight up and then go down, but must do so quickly as it'll continue to rotate. If any part of the ship touches an object or the wall, then they will lose health. While you aren't allowed to make the Helirin stop, you can change the position and in some cases the speed. To change the direction it rotates, the player must hit certain special objects that will cause your ship to do so automatically. At the beginning of each stage, the character will have three hearts. Hitting a wall will minus the player of one heart, and once all hearts have been depleted, they'll have to start the entire stage over. There are certain areas in each stage that will replenish your hearts.
Two sequels, Kururin Paradise for the Game Boy Advance and Kururin Squash! for the GameCube, have been made in 2001 and 2002, respectively. Unfortunately, none of them ever made it to America. Helirins, of which there are many different kinds, have appeared in the Wii video game Super Smash Bros. Brawl. In it, they appeared as trophies and as Assist Trophies, where they would become an obstacle that is hard to get past, especially if they push the player over the edge. They also appeared in the game's predecessor Super Smash Bros. Melee as a trophy.
The game was later put on the Wii U's Virtual Console service where in 2016, it first released in North America.
