How can I light up the Underground?


Hint 1 of 7:
Did you try your lantern?

Hint 2 of 7:
Hmm...well, perhaps you could "let the sun shine in".

Hint 3 of 7:
Have you seen anything that could reflect well on your chances?

Hint 4 of 7:
Don't continue on until you have visited the Royal Castle.

Hint 5 of 7:
By using the jar, you can create mirrors and use them to reflect light into
the Underground.  However, you can't reflect light in from a Shady area.
