Alice In Wonderland :

Alice, a young girl, sits bored by a riverbank and spots a White Rabbit with a pocket watch and waistcoat lamenting that he is late. Surprised, Alice follows him down a rabbit hole, which sends her into a lengthy plummet but to a safe landing. Inside a room with a table, she finds a key to a tiny door, beyond which is a garden. While pondering how to fit through the door, she discovers a bottle labelled "Drink me". Alice drinks some of the bottle's contents, and to her astonishment, she shrinks small enough to enter the door. However, she had left the key upon the table and cannot reach it. Alice then discovers and eats a cake labelled "Eat me", which causes her to grow to a tremendous size.
