Puck, also known as Robin Goodfellow, is a character in William Shakespeare's play A Midsummer Night's Dream, based on the ancient figure of Puck found in English mythology.
Puck is a clever, mischievous elf, sprite or jester that personifies the wise knave. In the play, Shakespeare introduces Puck as the "shrewd and knavish sprite" and "that merry wanderer of the night"; he is a jester to Oberon, the fairy king. Puck and Bottom are the only two characters who interact and progress the three central stories in the whole play; Puck is the one who is first introduced in the fairies' story and creates the drama of the lovers' story by breaking up a young couple lost in an enchanted forest, as well as by replacing Bottom's head with that of an ass. Similarly, Bottom is performing in a play intending it to be presented in the lovers' story, as well as interacting with Titania in the fairies' story.
The audience is introduced to Puck in Act 2 Scene 1 when one of Titania's fairies encounters Puck and he replies:
Thou speak'st aright;
I am that merry wanderer of the night.
I jest to Oberon and make him smile
When I a fat and bean-fed horse beguile,
Neighing in likeness of a filly foal:
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 wither'd 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 quire hold their hips and laugh,
And waxen in their mirth and neeze and swear
A merrier hour was never wasted there.
Puck is Oberon's servant sent by Oberon, who is angry with Titania the fairy queen because he could not have the Indian boy/slave, so Puck is sent to fetch the flower that has been hit by cupid's arrows. Puck is then instructed by Oberon to use the love flowers juices to fix the love entanglement occurring between the Athenian lovers who also happen to be running about in the forest. He mistakenly administers the charm to the sleeping Lysander instead of Demetrius. Puck provides Nick Bottom with a donkey's head so that Titania will fall in love with a beast and forget her attachment to the Changeling Boy, allowing Oberon to take the child from her. (Oberon does so successfully.) Later, Puck is ordered by Oberon to fix the mistake Puck made, by producing a dark fog, leading the lovers astray within it by imitating their voices, and then applying the flower to Lysander's eyes, which will cause him to fall back in love with Hermia. The four lovers are then made to believe that they were dreaming what took place in the forest (hence the play's title A Midsummer Night's Dream). At the end of the play (Act 5 Scene 1) Puck delivers a speech in which he addresses the audience directly, apologizing for anything that might have offended them and suggesting that they pretend it was a dream:
