Moon Dust

Moon dust, believe it or not, is found on the Moon Island (Whoa! Surprising right?). It has a astronomical value, and sells for $75.

Although Snow and Moon Dust look almost perfectly identical, you don't have to worry about confusing them, since they are on the opposite sides of the map.

The best way to get to the moon (besides :fly) it go to the Base Island, climb the ladder halfway, equip a Respirator, wait until you have 20 oxygen, and then use a Condensed Joy. The reason you climb up halfway is because the condensed joy launches you so high, that if you use it at the top, you will end up landing on the moon so hard that you fling off.
