Groovy Carp is a species of Fish native to Termina that appears in Majora's Mask 3D. Spoiler warning: Plot or ending details follow. It is a small species of Fish that can be caught in the Swamp Fishing Hole. It can be found near thick vegetation and can be caught using the Sinking Lure. Due to their small size and the location they appear, Groovy Carp are useful in catching Ferocious Pirarucu (which requires Link to hook smaller fish in order for it to bite). Spoiler warning: Spoilers end here.
