Section 9 Underground Cavern
Underground Cavern is down from Chasm and south of Underground Passage. "Tentacles of fungus hang down from the roof of the cavern like stalactites in this expansive series of caves, perhaps the root system of the forest above. Light filters in from above. The caves continue north."
The fungus tentacle is a person and scenery in underground cavern.
The Morality Module is in Underground Cavern. "One of the modules is stuck to the end of a tentacle fungus."
Instead of taking the Morality Module in Underground Cavern:
if the small rock is unthrown:
say "You reach for the module, but the tentacle expertly tosses it to another waiting tentacle.";
if the small rock is thrown:
continue the action.
After throwing the small rock at the fungus tentacle:
say "You pitch the rock at one of the fungal tentacles and it drops the module.";
now the initial appearance of the Morality Module is "There is a module on the cavern floor."
The small rock is a thing in Underground Cavern. The description of the small rock is "Personality module sized."
