Chunky is the only Kong who talks with the Worm, who is located near Funky's Store. It explains to Chunky about its issues with the Tomatoes surrounding its house. Worm explains that the Tomatoes ate all of its friends, and claims to be the only survivor of them. It offers Chunky a Golden Banana for destroying the four Tomatoes. To do so, Chunky must turn into his Hunky Chunky transformation from a nearby Kong Barrel to squish the Tomatoes.
The Worm does not reward Chunky yet, as it asks him to relocate its house to a sunnier location, because it dislikes the constant rainfall in the current area. Still under his Hunky Chunky transformation, Chunky must pick up the Worm's house and place it on a dirt patch near the cuckoo clock tower. The patch depicts the Worm's own house. By doing so, the Worm thanks Chunky and rewards him with a Golden Banana.
