In some pulp fiction works, monkeys might be associated with adventure themes. They could be found in jungles that the heroes or villains are exploring. The monkey could be a source of chaos or an unexpected helper. However, without more specific context, it's hard to define a very precise connection between'monkey' and 'pulp fiction' in general.
There could also be a connection in terms of the vivid and somewhat wild nature of both. Pulp fiction is known for its flamboyant, action - packed, and often strange stories. Monkeys, with their energetic and unpredictable behavior, could fit well into the crazy and exciting worlds often depicted in pulp fiction.
