When the Light Switch is off, Pikarin moves quickly, constantly pursuing the player. In this mode, it has an angry expression on its face.
When the Light Switch is turned on, Pikarin moves slowly in a straight line until it collides with a block, bomb, or other enemy, at which point it pauses and then chooses a random direction and continues to move. It may choose to reverse directions even if it is not at a dead end. In this mode, it has a tired expression on its face.
It will harm the player on collision, and takes 2 hits to defeat.
The name "Pikarin" comes from "pika", a Japanese sound effect for a flash of light.
