Dr. Vu items

You get them in the same fashion that you get Land expansion items, Storage upgrade items, Beach and Mountain expansion items.  You get them through popping opinion bubbles.  They're rare.  You may be able to find some for sale, but be quick.  They sell quickly.  I usually find items for sale when I'm actually looking for something else.  I try to always have extra cash just in case I run across some.

Sometimes you also get them when visiting another city and tapping the Blue Gift.  Sometimes they are available to buy in the Global Market.
