Adults can choose between being students or teachers, there are costumes for Dumbledore and Hagrid, as well as nasty scary creatures like Dementors.
Aided by Hagrid, the Hogwarts groundskeeper, and his schoolmates Ron Weasley and Hermione Granger, Harry will cross paths with Voldemort again, battle a troll, outwit a three headed dog, and discover the true value of friendship.
The character Hagrid speaks with a very thick dialect and it's hard not to stumble through his words, but reading slowly through his dialog allows the reader to really hear the voice of this character.
