Shout out to my first attempt on the final boss fight against Squid, during a run where I intended to finish the game normally (I've completed the game twice with the alternate ending...). He immediately tells me to take a break, and so I spend the next 30 minutes getting to level 100 in the smiley minigame to avoid going back to the fight.
(Video edited to just the Squid bits that make my brain buzz with the good chemicals.)
