Keroppi Hasunoue (はすの上 けろっぴ, Hasunoue Keroppi) (also known as Kerokerokeroppi) is a frog character with large eyes and a V-shaped mouth. Keroppi loves adventure, and his bubbly personality makes him popular around Donut Pond. He has a brother called Koroppi and a sister called Pikki. Most often he is seen with his little snail friend Den Den, always tagging along a little behind. Keroppi is a fantastic swimmer and singer (but not at the same time). Keroppi has appeared in video games, including Kero Kero Keroppi no Bouken Nikki, Kero Kero Keroppi no Daibouken, and Sanrio World Smash Ball!. Keroppi was created in 1987 and his birthday is July 10. 1988. His hometown is Donut Pond and he lives in the Kero Kero House. Some of Keroppi's friends include Keroleen, Noberun, Kyorosuke, Ganta, and Keroppe, Den Den, and Teru Teru. His mom named Keroma owns a small restaurant and cooks Keroppi's favorite food—rice balls. His dad is named Keropa and he works at the Hasunoe Clinic with another doctor from Sanrio's Pokopon's Diary. Other family members include Kerobah, Keroppi's grandma; Kerojee, Keroppi's grandpa; and Chippi, Keroppi's little cousins. "Kero" means "frog's croak" and "Hasunoe" means on a "lily pad".
