Frantic Aspic is a choppier and less rhythmic song than Deluge Dirge that focuses more on the cello than the others. It only plays during Salmon Run wildcard rotations. The start of the piece features fast-paced cello and timpani notes playing at the same time. The song has a heavy emphasis on syncopating drum rhythms, making the piece seem very disorientating, which is a common trope of ω-3's music. The constantly changing time signature and fast tempo also contribute to this. Further on, there is a timpani solo, followed by a cello solo which plays the same rhythm, which then combines with a synthesizer solo. This song was added to Splatoon 2 in Version 4.0.0 and can also be heard in Squid Beatz 2 after being heard in-game, with a maximum score of 150 on Normal difficulty and 323 on Hard difficulty.
"Frantic" could refer to the song's fast tempo and hard-to-recognize time signature. "Aspic" is a food which is a savory jelly made with meat stock and is set in a mould. Fish is a common ingredient used in aspic. "Frantic" could also reference the special waves, in which it is typically harder to get Golden Eggs, so the players are frantically running to collect them.
