They're essentially cards that vanish after a while and they're pretty hard to get. All you can do is look.
To get you started:
Hogwarts Exterior
Run down the first set of stairs,turn left and run to the far end of the screen where the three blocks are. There is a gap in the wall beside the cliff. Run down and grab your first vanishing card. NOTE: You have to do this quickly or the card vanishes(what a surprise).
Now that you know what they look like you'll spot them a lot easier.
Keep it cool

Thanks. I too have been looking for the vanishing cards. Any other tips on their locations in different levels?

Anyone had any further luck with cards?

I know on Moodys challenges, the 3rd challenge, destroying the walls with the pots, when you start it, grab a pot and destroy the wall directly in the middle, then walk round it. The card is behind it.

Hope this helps.

I looked for hours for this one!! I finally got it!! Thanks so MUCH!!!

How do you get one in herbology and the prefect's bathroom?

the one in herbology is when u start the second time u go back to the big room and open the pads to the right and there it is but i dont no where the prefects bathroom is

I do know where the one in the Forbidden Forest is. The second time u go through go straight to where you met the fir e salamanders but it's in the middle of all the mushroom behind the wall

In the prefect bathroom when you go back in, go to the left past the dragon statue and the fish statues, past the salamders and up between the next 2 fish statues is where the vanishing card is

Whoever invented the voldemort part of this game is stupid! i cant aim the stupid flare and i keep hitting my self. How did anyone else do it?
