Overview:

The Gummies find a Gummiscope, a gigantic machine that harnesses sunlight as a means of long-range communication, that could allow them to make contact with the Great Gummis across the ocean – but it can also be used as a weapon, causing Duke Igthorn to use it as a laser-type weapon to force King Gregor into surrender.
