"A Matter of Monsters!" represented the fourth part of the continuing series, The Keeper's World, and it initially appeared within Pizzazz 4 during January of 1978. The complete narrative sequence was republished in the United Kingdom in issues Star Wars Weekly 47–50 spanning 1978 and 79, as well as in the limited edition comic book Star Wars 0 that came out in 1999.
Following their emergency landing on Keeper's World, Luke Skywalker, Leia Organa, C-3PO, and R2-D2 find themselves under assault by a local monster. R2-D2 is successful in locating and rousing the creature's parent, who then takes the monster away. However, just as Leia Organa believes that they have reached safety, an Imperial fighter appears, entering the planet's atmosphere.
