Ok, I know this will be a long post, but...can someone please help me find..

I don't know if I have found them all but there are too many to put on this page so just keep looking some of them require you to learn certain spells before you can get them so just look and look and make sure you mark down where you have been so you don't get confused.

Spongigy rug: There are two parts. By the diffindo challenge entrance there is part of the wall with a scar. Cast alohamora and then diffindo then lumos on the gargoyle. This causes a passage in part of the wall (the one to your left if your standing at the entrance to hogwarts looking outside) to be opened. Go up the stairs. To the right of them is a square stone JUMP ON IT. IT CAUSES PART OF THE WALL TO SLIDE AWAY AND A LITTLE ROOM TO APPEAR WHICH CAN BE REACHED BY THE SPONGIFY RUG.

O yeah and there is s similar type thing in the room just beyond the hospital ward (just thought might mention it as you probably haven't done this either). Yeah, as soon as you get in the room you there is a square on the floor which you jump on. This cause a panel to slide away in the wooden bit overhead. It can reached by the spongify rug. You may have already done this but thought I would add it anyway

The fun of the game is getting to find all the secrets yourself. If you get stuck and can't find any more, just start walking around trying to cast on everything. Plus I don't have time to type up a walkthrough of all the secrets...
