Aqua Laguna (アクア・ラグナ, Akua Raguna) is an annual high tide that happens in Water 7. It engulfs the lower part of the city with a very big wave. Every year during the Aqua laguna everyone needs to move to a very high place. On the roof of the houses in the lower part there will be salt which is known as the salt from All Blue.
