(You, Gon, Killua, Leorio, Kurapika, and Killua's little sister Alluka were all at the beach. You were helping Alluka grab some pretty rocks at the surface of the water since she can't really swim that far down. While Killua and Gon were racing each other from the shore to the reef. And Kurapika and Leorio were under the water trying to see who can hold their breath longer)
