Fishing Frenzy starts off with a timpani sequence, accompanied by an electronic whine similar to an alarm. The electronic production then builds up, as cellos and more drums are added. Later on, there is a synthesizer solo, which features many fast-paced rhythms and notes. The song plays during Known Occurrences in Salmon Run matches, replacing Deluge Dirge or Frantic Aspic. It can also be heard in Squid Beatz 2 after hearing it in a Salmon Run match, with a maximum score of 140 and 333 in Normal and Hard modes, respectively.
Frenzy pertains to an emotional state of wild uncontrollable behavior, fittingly describing the state of the Salmonids, and even the Grizzco workers. Fishing refers to the Grizzco workers harvesting the Salmonids' Golden Eggs, and utilises alliteration.
