Green Slimes: another cleaning crew member, also drawn from ‘50s Hollywood horror flicks.
The Cleanup Crew: ochre jelly, black/gray pudding, green slime, gray ooze, yellow mold. Excellent general use monsters due to their nature as scavengers and carrion feeders. These can be troublesome due to common modes of attacks actually working against the attacking party.
Horses: only war horses melee; so what is a war horse? We originally interpreted this as a matter of training versus type of horse. Later we revised it to apply only medium and heavy horses could be trained as warhorses.
Mules: the note [o]nly mules are agile enough to be taken in dungeons encouraged the nearly universal presence of a mule or two in adventuring parties.
Insects or Small Animals: introduces the a hit equals a kill idea into the rules, for those who have no experience with Chainmail.
Large Insects or Animals: besides a brief mention of Barsoomian creatures from Burrough’s works of fiction, we are also introduced to another new concept. If the referee is not personally familiar with the various monsters included in this category, the participants of the campaign can be polled to decide all characteristics. This highlights the do it yourself attitude of the original play style.
Other Monsters: suggests Titans, Cyclopes, Juggernauts, Living Statues, Salamanders, Gelatinous Cubes, Robots, Golems, Androids; as additions to a campaign. Many of these would be described in Greyhawk, all were listed in one edition or another during the pre-1983 era of the game.
