From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Chenshi is a baby who lives in Chao's Village.
Ginkaku and Kinkaku attacked Chao's Village. They had a man-eating gourd which swallowed anyone who did not reply when called by name, and so they gathered the villagers up and called out their names. There was no way that the two-week-old Chenshi could reply to his own name though. Terror forced Chenshi's Mother to tell him his name so that he could call it out. Luckily, Son Goku had arrived to get rid of Terror and Plague at Chao's request. Unable to tolerate the situation, he dashed in and put a stop to the two and Chenshi was spared.
His character design is the exact same as that of Turbo Norimaki.
