Prince Vladimir offers Alyosha Popovich to sit next to him, but Alyosha Popovich refuses and decides to take the lowest place in the social hierarchy by sitting next to the stove. At the feast, the monster Tugarin insults the Prince by sitting between Vladimir and his wife. Tugarin also does not pray to God and gorges himself at the feast. Alyosha Popovich, who is disgusted with the way Tugarin is acting, insults the creature with stories about the deaths of a dog and a cow. Tugarin is provoked by these stories and throws a dagger at Alyosha Popovich. Then, Alyosha Popovich accepts Tugarin's challenge to fight. The battle takes place in an open field, and when Alyosha Popovich arrives, Tugarin is already flying in the sky on his wings made of paper. Alyosha Popovich prays for rain, and Tugarin falls to the ground because his paper wings get wet. Finally, Alyosha Popovich knocks Tugarin's head off with his staff, sticks it on a spear, cuts his body into small pieces, and presents it to Prince Vladimir's court.
