Potioncat:
As a fellow believer in the boggart-is-not-the-moon (I think we number 
at approximately two) I'll toss out some possibilities. And they 
wouldn't have to make Lupin ESE. (I believe in ESE!Lupin on alternate 
days.)

It's a prophesy orb. It's the lights at St. Mungo's. It's a bubble of 
droobles best blowing gum. It's a cockroach egg.

JKR may have used the bit of dialogue between Lupin and Hermione to 
tell us that the boggart was the moon. Just like the digalogue "part of 
a gang of Slytherins" told us Snape's House, but, except for that one 
time, it is never called a moon. Many readers think "orb" is a red 
herring, I think Lupin's calling it a moon is a red herrring.

I also think there is a clue or a connection between the orb disolving 
into a cockroach and the jar of cockroaches that crashes over Harry's 
head.
