I'd like to point something out, regarding that adventure, and the celery.
I have seen more people asking where the celery is on message boards than asking for help with any other adventures. This adventure was in the first batch, and it seems that since then, the characters are sure to pretty much tell you where the items you need are. I think there was so much confusion about the celery that it prompted the game writers to make sure to give better clues about where stuff is.
For my part, and I've read other people say the same thing, I actually checked Mr H's office first when I needed celery. He's a rabbit, so it just seemed logical.
