Here is what Wikipedia says about Puck:
Puck is a clever and mischievous elf and personifies the trickster or the wise knave. In the play, Shakespeare introduces Puck as the "shrewd and knavish sprite" and "that merry wanderer of the night" and jester to Oberon, the fairy king.
Sometimes Puck is seen as a Satyr, and that is the Puck I am sculpting. I've always wanted to do a Satyr!
