After escaping from the sinking island with Tummi and Gruffi in the episode "My Gummi Lies Over the Ocean", Gusto and Artie moved into a bluff near Gummi Glen which is on the side of a cliff behind a waterfall. Gusto uses the waterfall to power an elevator to take him up and down the falls, similar as to how he used a elevator made of pulleys and bamboo to build his masterpiece of the dragon statue when he was on the island. Gusto and Artie live in an alcove behind the waterfall which serves as a makeshift apartment, where Gusto does most of his work. Presumably the waterfall was named after Gusto once he moved it. Although Gusto and Artie live in Gusto Falls as they prefer peace and quiet, they often visit the Gummi Glen Gummies, and will move into Gummi Glen when it is too dangerous to be at Gusto Falls, such as upcoming natural disasters or winter weather.
