Father of the Sexiest Lobster

Father is an ordinary lobster that only cares about raising his Son right. The ocean is a dangerous place, but they survive and thrive together as a family. His Son, winner of the Third Annual Sexiest Lobster Competition, is the target of an abduction that leaves Father alone and hopeless. He has no money for the ransom, and no skills that he could use to save his Son. When Father decides nothing can stop him from saving his Son, a system asks if he wants revenge and sends Father on a time looping rampage across the ocean.
