Black Jack: Dr. Pinoko no Mori no Bouken - Dec 17, 2005

Dr. Black Jack forgot his doctor's bag, and his assistant (plus self-claimed "wife") Pinoko rushed to deliver the bag but found herself lost in the forest. Guided by a butterfly, she found that many animals in the forest are sick or injured, and Pinoko used her knowledge to help those animals. (Source: ANN)
