Mr. Gunk tries to attack the Wonderbot, but Rodney stops him, resulting in him falling into a tub of oil. He then fires Rodney and scolds Herb.
He is not seen again until the end of the movie. Herb is working when Lydia appears and urges him to come outside and see Rodney. Mr. Gunk angrily tries to stop him and force him to return to his work. However, fed up with his boss, Herb dumps his dishwashing machine over Mr. Gunk's head.
