Swim This Way
"Swim This Way" (ミュージカルは楽し, Myūjikaru wa Tanoshi?, lit. "Musicals are Fun") is the first Song Mission sung in Atlantica in Kingdom Hearts II. Sora must first complete Timeless River and complete the Splash Island Gummi Route for the first time. Then enter Atlantica and finish the swimming and Musical practice with Flounder and Sebastian.
It focuses on their rehearsal for Atlantica's Annual Musical. In order to pass, the mission requires four "Excellents" in a row to fill up the Music Bar with enough notes.
