Granny Ttongbokki 3: There's No Such Thing as a Bad Kid What's up with Granny Ttongbokki's special delivery service? Buckle up and let's find out! Granny Ttongbokki, who runs a tteokbokki shop in front of Haetsal Elementary School, is a real hero to all the kids who know her. The director of Haetsal Elementary, however, who has never made a secret of his dislike for her, claims that her tteokbokki is unsanitary and forbids all the students from going to the shop. With her main source of customers gone, Gran thinks of a new scheme. Dubbed "Knock Knock! Tteokbokki at Your Doorstep," it's a delivery service that includes Gran making customers fresh tteokbokki at their home. There's something fishy, however, about all the customers who order the new delivery service. Bomi, the first customer, orders tteokbokki for her birthday party. At her house, everything's ready for the party except one thing: the guests. Whatever happened to Bomi that none of her guests came? The second person to order the delivery service is none other than the director of Haetsal Elementary, Gran's sworn adversary. What kind of "special" tteokbokki will Gran prepare for the director, a money-grabbing opportunist who cares nothing for the children of his school? Stay tuned for Granny Ttongbokki 3: There's No Such Thing as a Bad Kid and Gran's special delivery service that will surely appeal to all kids who just need someone to listen to them.
