Kaguya appears as a woman with rabbit ears sitting on a floating mat. Start the battle by shooting at her face. Soon, her fan will break and then she'll start shooting strange neon rabbits. Go up and down avoiding these while shooting at her face. After breaking off her ears, she will start making all kinds of strange-shaped rabbits. Avoid these and finish her off.
When defeated, the boss is revealed to be a wood cutout made by two penguins, with a radio for the voice. After a few seconds, the penguins will run away.
