Appreciating Frith's talents as a designer, Jim Henson brought him on board his creative team.
One of Frith's early projects was designing characters for The Land of Gorch, a segment of Saturday Night Live.
"Fraggle Rock" is the new show which emerged and subsequently ran for 4 seasons totaling 96 episodes between January 10, 1983 and March 30, 1987.
He explains that he drew on two major parts of his background when creating the "look" of the show, the first his many years in working with Ted Geisel (Dr. Seuss) on several children's books and the second being his growing up in Bermuda.
[8] In October 1995, Frith left Henson Productions to start a new company, Sirius Thinking, Ltd., with John Sculley, Christopher Cerf and Norman Stiles.
[citation needed] Frith, along with his wife, Muppet performer Kathryn Mullen, founded "No Strings" along with emergency aid worker Johnie McGlade.
In the film, "The Story of the Little Carpet Boy", one puppet loses several limbs before he learns to avoid land mines completely.
