Everyone! I just had a stupid idea

A sea themed HHW Gacha set. The song would be Deep Sea Town. Kanon and Kaoru would be the 4 stars. It would be a cool type set. All of the outfits would be sea creatures themed, like Kanon as a jellyfish or Hagumi as a clownfish. I would imagine they would either go diving, or they would go to some place like Seaworld.
