Meanwhile, Mime Gopi, who is a big don has belief in astrology. He takes care of a fish named Kattappa under the belief that it brings him good luck. In the midst of all this, Yogi Babu steals the fish and drops it in a water lorry. In the end, the fish ends up in the hands of Livingston, who runs an aquarium house. Chandini Tamilarasan, who is an air hostess and a childhood friend of Sibi decides to give him a surprise and gifts him the fish. At the same time, Mime Gopi is frantically searching for the person who stole his fish.
Whether Mime Gopi manages to find his fish or not and Sibiraj, who has been called an unlucky person redeems himself amidst the fish's presence forms the rest of the plot of Kattappava Kanom.
Sibiraj has taken up a role that has absolutely no scope for any action sequences and has performed the comedic role to a tee. He has done his part as per the story's requirements and has not exaggerated at any juncture. That deserves applause. Aishwarya Rajesh comes as a modern girl and is shown indulging in drinking alcohol and drugs. Her character in the film is quite bold and she has performed her role with ease. In addition, she surprises everyone by speaking double meaning dialogues throughout the course of the narrative. Kaali Venkat, who has been added in the cast as the comedic relief does a satisfactory job. Chandini Tamilarasan, who comes in as Surprise Sheela is a joyful character and leaves a smile on everyone's faces. Although Mime Gopi appears for only two or three scenes, he has done his job well to convince us that he can be a menacing villain. Yogi Babu has less screen time, but leaves a mark yet again. Chitra Lakshmanan, Kalavani Thirumurugan and Saravanan have done their roles amicably.
Director Mani Seiyon has attempted to make a film that addresses the issue of superstitions that exist in our society. His attempt at churning out a story with enough humorous content leaves us satisfied for the most part. The only obstacle comes in the form of the double meaning dialogues that only leaves us cringing. Had they been avoided, the film could be watched by families too and would have been more enjoyable. Anand Jeeva's cinematography is top-notch; especially in the scenes filmed inside the house. The songs in the film are average, but Santhosh Kumar Dhayanidhi's work in the background score department deserves appreciation.
In short, Kattappava Kanom is a comedy feast.
