The boss with Fark is peculiar because like Romalo, the damage is fixed, kinda like how Spark's health meter is divided into parts. The weapon used in Fark's boss does not matter because DPS is practically nonexistant, so using the Board to reach him is the best strategy. Do not even bother fighting the robots, Fark is still vulnerable while he's up in the air, so use the board to beat him way way faster. This fight is actually skippable in Fark's Story and Spark's Challenge, and oh trust me, I'll get onto that. While way better than my Smog City run, I did stumble very stupidly in one section, so don't think I'll leave it at that forever.
