Grouper

A Grouper is a type of fish that turns your pet into a Creeping Widow. A fingerling grouper turns your pet into a Creeping Widow for 120 seconds but a small grouper can turn your pet into a Creeping Widow for 300 seconds. A Flawless Grouper can turn your pet into a Creeping Widow permanently, and it can only be reversed by feeding your pet a dogfish.
