Eyti moves slowly. When it reaches the edge of a platform or when it collides with a bomb or wall, it will pause before reversing its direction. If the player lines up with Eyti horizontally, and there are no obstacles between them, it will pause briefly before dashing in the direction of the player. It will harm the player on collision.
Yeti moves around aimlessly until it decides to curl up into a ball and bounce, pursuing Bomberman quickly and ceaselessly. It will only stop bouncing if it is caught in an explosion, at which point it will revert to its initial movement pattern. It will teleport away if a bomb is thrown at it or carried near it while it is walking.
