All except the hufflepuff. I'm a slytherin but hufflepuff isn't an insult<< I am also a fellow Slytherin and found that quite rude. Also, does no one remember Cedric Diggory? He was a Hufflepuff and he was awesome!
Cubone Theory - I have always felt like this was true. Now I really thing it is. Cubone is a baby Kangaskhan . Like this post says, Cubones wear the skull of their dead mother. I feel if this theory is true, no one will be surprised.
