Character in William Shakespeare play A Midsummer Night's Dream also called Robin Goodfellow (4)
I believe the answer is:
puck
(Other definitions for puck that I've seen before include "gets knocked about with sticks" , "Mischievous character" , "Mischievous sprite, Robin Goodfellow (AMND)" , "one spun across the ice" , "Disc used in ice-hockey" .)
