The majority of the "Underdog" adventures were presented in the form of four-part serial episodes. Other cartoons, including "Go Go Gophers" and "The Hunter", filled the middle segments. A 1969–1973 NBC run featured all four parts of an "Underdog" storyline in one half-hour show. The series was first syndicated in the U.S. in the mid-1960s under the title "Cartoon Cut-Ups," which presented two "Underdog" segments along with "Tennessee Tuxedo and His Tales" and "The World of Commander McBragg." This package was revised in the 1970s under the "Underdog Show" title, now including all 124 "Underdog" segments and featuring "Tennessee Tuxedo," "Commander McBragg," "Go Go Gophers," and "Klondike Kat" in various episodes. A syndicated package prepared for distribution outside the United States (which also aired on the Boomerang cable network) usually featured two brief "Underdog" episodes in a single show along with a wider variety of other Total TV cartoon shorts which appeared between such segments: "Go Go Gophers," "The King and Odie", "Klondike Kat," "Tennessee Tuxedo," "The Hunter," "Tooter Turtle", and "Commander McBragg."
