Chalien

The Chaliens (also known in Japan as the Chailiens or Chee-Chai Aliens) are small aliens that come from the Petit Galaxy. There are 113 different types of Chaliens, as well as a few related characters in the series.

In Chee-Chai Alien, Chaliens can be attracted from artificial light sources using pheromones. Chaliens (prior to game completion) appear with dark matter on them, and also like to play in a large room known as the Polariton. Many different Chaliens have their own unique minigame, or participate in the default minigame known as Kachinuki! Kurukuru Battle.

Li'l Blue is the flagship Chalien of the franchise, who serves as the mascot for Chee-Chai Alien (with Saraba), Nonono Puzzle Chalien and Spin Six.
