i hate the chapter 5 secret boss so much

i am currently stuck on the secret boss for chapter 5 of deltarune. the secret bosses have always been my favorite part of deltarune, and for spamton, jevil, and gerson i even made a save file just to be able to fight them whenever i want. but this secret boss is so annoying. firstly, before you even fight it, its such a random boss. the other bosses had interesting stories and were connected to the other characters in a meaningful way. jevil was seams former friend and court jester that went insane, spamton is a washed up salesman that used to be so high up he was in the queens mansion, johnathan mantle knows about the weird route and is just pretty intruiging. gerson is a dead teacher brought to life by the dark fountain that trained susie, and then this boss is literally just a copy-pasted obscure undertale character that has no connection to the actual plot besides one shop where you dont even know its them, and orange talks before the battle. like it seems toby forgot to put in a secret boss and just took one from a wheel of minor undertale characters. then, the fight itself is annoying. i havent beaten yet, but i swear the attacks are not fair at all. especially the bombs, like you have 0 time to react. its not even hard in a fun way, like the knight is, its just a pain in the ass. with knight, i felt i was getting better every try. here, i always die in the same spot. i think this is partially because there are barely any good heals in the chapter, not any revive mints and only 2 group heals. i know that seam tells us we should get the mannequin, but does toby really expect us to make it this far, than completely reset our save to chapter 2 just to fight a secret boss? they should have at least given us a way to retrieve it in castle town. ive heard some people like it because trans vocaloid, and if thats why, thats fine, but i am cis and dont like vocaloid so i really just have no reason to like the fight at all.
