Hi everyone,

I'm re-reading PoA, and I came across something that I'm hoping 
someone has a theory about.  In the scene where Harry's class is 
dealing with the boggart in the wardrobe, the following occurs...

"'Here!' shouted Professor Lupin suddenly, hurrying forward.

_Crack!_

The legless spider had vanished.  For a second, everyone looked 
wildly around to see where it was.  Then they saw a silvery-white 
orb, hanging in the air in front of Lupin, who said '_Riddikulus!_' 
almost lazily.

_Crack!_

'Forward Neville, and finish him off!' said Lupin as the boggart 
landed on the floor as a cockroach..."

Now, I had always assummed that the boggart turned into the moon for 
Lupin, although I have read some of your posts which suggest that 
Lavender was correct when she wondered why he was frightened of 
crystal balls.  Either way, for the life of me I have not been able 
to figure out why turning either the moon (or a crystal ball for that 
matter) into a cockroach would make it funny.

Can the boggart be something else entirely?  If so, what?

Toni (who is sorry if this has been discussed in the past, but can't 
figure out how to look anything up!)
