You know, I'm actually having to do some research to answer some of these questions...
1. Is it an animal?
No!2. Is it a place?
Yes!3. Is the place west of the Misty Mountains
? Yes... in a manner of speaking.4. Does Bilbo ever visit there?
No.5. Is it the Mines of Moria?
No.6. Is it someplace the Fellowship goes to?
No.7. Is it a bad place (as in evil or "on the dark side")?
Not originally...8. Is it underground?
Heh... no... but... you're on the right track... kind of9. Has Gandalf been there?
This one I had to research. Almost certainly, no. And 100% certainly, Gandalf
would never have been there.10. Is it The Misty Mountains?
Ha, I like the way your mind works. No.
