And sometime lurk I in a gossip’s bowl
In very likeness of a roasted crab,
And, when she drinks, against her lips I bob,
And on her withered dewlap pour the ale.
The wisest aunt, telling the saddest tale,
Sometime for three-foot stool mistaketh me;
Then slip I from her bum, down topples she,
And "tailor" cries, and falls into a cough,
And then the whole choir hold their hips and laugh,
And waxen in their mirth and neeze and swear
A merrier hour was never wasted there.
– William Shakespeare
A Midsummer Night’s Dream, Act 2, Scene 1. We learn from prankster Puck that he is a skilled shapeshifter. He can change physical form to become a "roasted crap" or "three-foot stool." He uses his magical powers to play practical jokes on the villagers.
