那年夏天

拉瓦的母親把他送到海邊和他年輕的叔叔住在一起，他馬上開始工作。一天，他發現一個人被衝上了岸。在醫院裡，Wut醫生診斷出這個人患有健忘症，他的叔叔自願將Lava作為他的看護人。熔岩命名他為波，並重新分配他所有的職責給陌生人。Wave對體力勞動的挑剔和無能令人驚訝，暗示著它過去的驕縱。                                                                    　　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.
