Why, Charlie Brown, Why? (1990)

Why, Charlie Brown, Why? is the 33rd prime-time animated TV special based upon the comic strip Peanuts by Charles M. Schulz. It originally aired on March 16, 1990 and was also nominated for an Emmy. In a departure of the light-hearted themes presented in previous (and subsequent) Peanuts specials, the story deals with a new character, named Janice, who is diagnosed with cancer. This is the first Peanuts special of the 1990s.

Storyline
A new girl comes to the neighbourhood school and Linus is smitten with her. Unfortunately, she develops the symptoms of leukemia and must go to the hospital for cancer treatment. Linus and Charlie Brown help her through the traumas of chemotherapy as best they can while Snoopy plays at being the world's greatest doctor.
