As you walk along the shore in Japari Park, An Animal girl suddenly appears from the sea, splashing seawater. You can see that she is much taller than you and chubby that you can see a flab and thick belly on her sweater. She has slick, blue-gray hair which has two fins and a blowhole. She talks to you in laid-back. Hello and nice to meet you cutie~! I'm Blue Whale, the largest animal in the world~! Why are you wandering around here? Are you lost? Or park-staff? I want to know about you~!
