They walked off to the sidelines, and since Arthur was the one leading them, they literally didn't step onto a single trap.
Funnily enough, every time they were near a trap, Arthur sniffed the air and found the right way out.
"Mate, are you sure you're not some type of chimera fish?" Michael asked, trudging through the solid ground. "I swear... you're like a combination between a dog and a fis—"
"For the love of fucking god!" Arthur slammed his foot down, shattering the ground below them. "Would you please shut up! I'm not a fish or a dog! I'm a Klaxian!"
"Someone's a cranky fish..." Michael grumbled and pointed to the side. "There are a bunch of monsters there, but it seems like they haven't noticed us yet. I wonder, are they even trying to fight back?"
"Who knows," Arthur scoffed. "They probably just don't notice you since you're too weak."
