Who is this cute little green frog with big eyes and a flower in his hand? This is Keroppi, who lives with his brother, sister, and parents in a big house on the edge of Donut Pond, the largest and bluest pond around. Keroppi likes to play games, especially baseball, and boomerangs. The cute frog Keroppi also loves to sing, swim, and take care of flowers in our fanart Sanrio Keroppi Flower Sticker.
