George's Marvelous Medicine (1981)

George lives on a farm, managed by his mother and father. Their lives are thrown into disarray by the arrival of Grandma, who behaves appallingly. George tries to make her 'better' by creating a marvelous medicine, which has the most extraordinary effect on Grandma, who grows and grows until she bursts through the ceiling. George's father realizes that the magic medicine could work on his farm animals, providing extra food to help feed a hungry world. But attempts to make more medicine lead to hilarious and frustrating happenings... The play uses puppets to considerable effect, plus a Giant Chicken, played by an actor.
