the author is trying to create a hateable kind of hero's party but not having common sense regarding of how a party supposed to work and the author just tryna put everything even if it is beyond ridiculous kind of plot to make sure the story itself will progress but that just doesn't work here
remind me again why did the hero party decided to kick out this MC again? he can control over many type of animals (which kind of giving him a lot of advantages) he can use them (such as this bee to paralyze the enemy) to help him during the adventure. I guess the hero party is just full of dumb...
