The adventurous and energetic big-eyed frog is a popular star in the doughnut pond. His unique skills are swimming (although he is not good at breaststroke, he is good at backstroke) and singing.

Dad is a doctor in the "Lian Shang Hospital", and mom is a good cook! There is an elder sister who likes climbing trees and cooking, and a younger brother who looks like him and likes studying machinery very much! A family of five lives happily in a doughnut pond.
