Pororo Movie: Badas-sog Daemoheom

Pororo and his friends travel beneath the sea to visit the Red Hunters, legendary guardians who protect the ocean from danger. Their excitement disappears when garbage, aggressive sharks, and the enormous sea monster Situs strike one after another.

Pororo and Crong are rescued by Merlok, but their friends are swallowed by Situs. Determined to save them, the pair joins Merlok's hunt for the monster, only to discover that his plan treats their friends as acceptable sacrifices. Pororo now has to stop the creature and the supposed guardian helping him, proving that saving the ocean means nothing if he abandons the people he came to rescue.
