I want Conroy's toupee.

Hint 1 of 8:

Now YOU'RE scaring me--it will come in handy, though.  Do you know who
founded the company that makes this game?

Hint 2 of 8:

That's right, George Lucas.  What's something else George Lucas is famous
for, in association with Steven Spielberg?

Hint 3 of 8:

Did you ever see "Raiders of the Lost Ark"?  For that matter, have you ever
played "Monkey Island 2"?  (Although Mr. Spielberg didn't have anything to do
with IT.)

Hint 4 of 8:

The alarm protecting the toupee works with the pedestal.
