Split & Splat

Split & Splat is a song by Chirpy Chips.

Description
Split & Splat was one of four songs added in the August Update. Like all battle songs, it has a random chance of being played during online matches. It can also be heard in Squid Beatz, and is included in Splatune.

The song has a rather upbeat and joyous tempo and feeling. The track starts with a repeating chip-tune rhythm accompanied with some chip-tune chord. After this, their is some singing, followed by a short instrumental break, and quickly returns back to some more singing.

In Splatoon 2, Split & Splat can be unlocked to listen in Squid Beatz 2 as a final reward from the amiibo with a maximum score of 147 and 226 in Normal and Hard modes, respectively. It cannot, however, be heard anywhere else in the base game.

Split & Splat (Stay Fresh Trailer)
The song was first heard in the Stay Fresh Trailer for the August Update. Near the beginning of the song, it moved one of the sections forward, leading to a longer instrumental opening, with vocals only coming in at around 25 seconds.
