Can someone help me find this track?

[Phos]

It starts at 15:33 when Pearl says "Booyah"
It has massive spoilers of the Octo Expansion so if you havent play it dont open the link LOL

It similar to the Battle Theme from one of the Splatfests but its not the same. i've been trying to find it for so long but i just cant find that version :c

I believe it’s this (near the end)?

Doesn’t seem like there’s an official name for it yet, or wasn’t at the time of the video’s posting
