Madeline adores her grandfather - she always has. To everyone else he might seem a bit strange - an eccentric inventor - perhaps even a little mad. Yet Madeline knows that these are his very best qualities.
One of Grandpa Gilderberry's most secret inventions is his box of potions which he delights in giving to Madeline each year on her birthday. Each potion conveys an unexpected and magical experience for Madeline, often to the frustration of her father. At one year of age, the red potion allows Madeline to breathe fire like a dragon and at two, the blue potion turns her into a mermaid for a day. Year after year, Madeline selects a new potion with exciting results, however each time she reaches for her enchanted birthday present, her grandfather reminds her of only one rule - 'don't drink the pink'.
Exploring the special relationship between a grandfather and his grandchild, the potions in Don't Drink the Pink provide an apt metaphor for each magical moment. Yet with birthdays comes aging and this tale doesn't shy away from what this means for both the young girl and her lovable grandpa.
