那年夏天

拉瓦的母亲把他送到海边和他年轻的叔叔住在一起，他马上开始工作。一天，他发现一个人被冲上了岸。在医院里，Wut医生诊断出这个人患有健忘症，他的叔叔自愿将Lava作为他的看护人。熔岩命名他为波，并重新分配他所有的职责给陌生人。Wave对体力劳动的挑剔和无能令人惊讶，暗示着它过去的骄纵。 Lava's mother sends him to live with his young uncle by the beach and he's immediately put to work. One day, he finds a man washed up on the shore. At the hospital, Dr. Wut diagnoses the man with amnesia and his uncle volunteers Lava as his caretaker. Lava names him Wave and reassigns all his duties to the stranger. Wave is surprisingly fussy and inept at manual labor, hinting at a pampered past.
