"A Matter of Monsters!" was the fourth installment of The Keeper's World, published in Pizzazz 4 in January 1978. The entire story arc was reprinted in the UK in Star Wars Weekly 47–50 in 1978–79, and in the 1999 limited-release comic Star Wars 0.
While stranded after their crash landing on Keeper's World, Luke Skywalker, Leia Organa, C-3PO, and R2-D2 are attacked by a monster. R2-D2 manages to find and awaken the beast's mother, who removes the monster. Just as Leia Organa thinks they are safe, however, an Imperial fighter enters the atmosphere.
