Gryffindor ties !!!
When you talk to other pupils look at their tie and you will notice that every one has a gryffindor tie on.
The only people with a different tie on are malfoy, crabbe and goyle (sorry about the spelling) and only two people have their shirts out (ron and seamus) and either crabbe or goyle (cant tell which) has not got a school jumper on. And you can change the colour of the hippogriff - after you save buckbeak - by going on hippogriff flight on the extras bit on the main menu.
