The Monkeys escape from the Banana Brothers Travelling Monkey Circus train early in the film and roam the woods, where they become antagonists for the Rugrats. Chuckie, frightened by the clown on the circus train, discovers the train first and points it out to the others, at which point they meet the monkeys. The monkeys play with the babies, stealing Chuckie's glasses and swinging through the trees, until Tommy attempts to feed Dil with banana-flavored baby food. This attracts the monkeys, and is the primary reason that the monkeys follow the Rugrats.
When Dil finally gets on Tommy's nerves, he considers leaving Dil with the monkeys. While he looks for the banana baby food, he throws Cynthia out of the bag and the monkeys take her. The monkeys hide from the storm until they attack the next morning, but are chased off by Chuckie and the others.
The monkeys are encountered one last time, where they are scared by Scar Snout on the bridge near the Ranger station. After this, they are reunited with Igor and Sergei and, to everyone's delight, attack annoying newscaster Rex Pester.
