Uncle Traveling Matt is a brave Fraggle explorer and Gobo's uncle on Fraggle Rock. In "Beginnings," he ventured out of the Rock to explore the human world of Outer Space. To document his exploits, Matt sends Gobo a series of postcards recounting his experiences with the Silly Creatures and their culture from the Fraggle point of view (such as believing skyscrapers to be edible like Doozer buildings). Uncle Matt prides himself on his bravery and resourcefulness, but also tends towards clumsiness, frequently falling backwards or tripping during his travels. He makes a brief return visit back to Fraggle Rock in the second season episode "Uncle Matt Comes Home," but in the fourth season episode "Uncle Matt's Discovery," he returns to the Rock for good. Although he still makes a few occasional trips to Outer Space, he mostly recounts his travels to the other Fraggles orally, as flashbacks are shown.
