"Tindera ng Balut" is a Tagalog horror animation about Aling Marta, a mysterious woman who sells balut (fertilized duck egg) in a small town. Her balut is famous for its rich flavor, and people flock to buy from her late at night. However, strange events begin to happen after townspeople consume her balut—some experience horrifying nightmares, while others fall ill or disappear mysteriously.

Pedro, a curious young man, decides to investigate after his friend goes missing shortly after buying balut from Aling Marta. As he digs deeper, Pedro discovers that Aling Marta is not an ordinary vendor. She has made a dark pact with a supernatural entity, using her balut as a tool to curse and trap the souls of her customers.

Pedro must now confront the dark forces behind the balut and stop Aling Marta before more lives are claimed by the sinister curse.

"Tindera ng Balut" combines Filipino street food culture with supernatural horror, exploring themes of greed, curses, and the dangers of making deals with dark forces.
