Here Comes Yo-Yo Ma! (4) (ヨーヨーマッが来る！ その④ Yō Yō Ma ga Kuru! Sono 4), originally Whistling (ヒューヒュー Hyū Hyū) in the WSJ release, is the six hundred seventy-fifth chapter of the JoJo's Bizarre Adventure manga. It is also the eighty-first chapter of Stone Ocean.
Summary
The guards discover Jolyne and Anasui hiding amongst the swamp fauna, aiming their machine guns toward them. As the two are distracted, Yo-Yo Ma sends mosquitoes from his mouth to Jolyne's face. The guards begin shooting, tearing up the boat. In response, Anasui punches Yo-Yo Ma towards the guards; he then walks toward their boat and hijacks it by using his Stand. The three continue their voyage in the Florida swamps.
Jolyne commands Yo-Yo Ma to stop whistling, and Anasui requests Jolyne to stop the same action, leaving her confused. She tries to talk to Anasui, but upon opening her mouth, she notices her tongue is filled with holes. Realizing she can't speak, Jolyne gestures to Anasui that the Stand is attacking her. However, Anasui misinterprets these gestures as advances on him. When gestures don't work, she resorts to force. Anasui is too dense to fully understand the situation at hand, and Jolyne stares down at Yo-Yo Ma, observant of its tricks and determined to defeat the Stand.
