Question: what does puck do in midsummer night dream?
Answer: Puck is the mischievous, quick-witted sprite who serves Oberon, the fairy king. When we first meet Puck, he has been sent by Oberon to find the flower 'love-in-idleness,' the juice of which can be spread over a sleeping person's eyelids to make that person fall in love with the first thing he or she sees upon waking.
