Promotional wraps for the new season of 'Naagin 7' have transformed sections of the Mumbai and Delhi Metros into 'Naaglok Ki Train.' The eye-catching snake-skin designs and branding on Mumbai Metro Line 1, a busy route connecting Ghatkopar and Versova, have garnered significant social media attention. Commuters shared videos and reactions, with many joking about encountering a 'real Naagin' or calling it the 'height of advertisement.' The franchise's producer, Ektaa Kapoor, also shared a Delhi Metro promotion, amplifying the buzz.
