Expecto Patronum is the first and only moment in Harry Potter and the Prisoner of Azkaban, Chapter 12, The Patronus.


I’ll have to think carefully about how we’re going to do this … we can’t bring a real Dementor into the castle to practise on …

This moment has 2 zoom levels.

Zoom 1

  • Unlock "Dementors and Chocolate" by clicking on the book on Harry's desk
  • Andros the Invincible's frog card is hidden inside a drawer in the desk in front of Harry.

Zoom 2

  • The bean is found in the desk next to the one where you found the card.
  • In the very back, there is a cabinet where you can find a bag containing five galleons at the bottom.
  • When you mouse over him, Professor Lupin forces the boggart (in the form of a moon) back into the chest, which then continues to shake and rattle.


The fire crackles softly, and you can hear the wind, with the occasional drip of some sort of liquid (presumably water), in the background.

  • Drawers make a sliding sound when opened
  • The cabinet door creeks when opened
