"How should I know? I already said before that monocle of yours is a new thing to me. How do I know how it works? However, this Swamp Croc does have a camouflaging ability that could deceive a hunter's senses. So maybe it works the same way to your radar."
'But my radar can still track creatures in hiding like that Land Behemoth from before. I knew that it is a monster despite it pretending to be a hill.'
"It was not pretending, it was simply sleeping. You lot were the ones that mistook it for a hill. And I said ability, not simply hiding. This Swamp Croc has an inherent ability to trick sensing ability. I think it is more or less like the invisibility effect of your Cloak of Shadow. I bet if someone else uses that cloak of yours to become invisible, he or she will not be detected by your radar as well. That's why you were able to escape Winston's detection. Do you think such a high-level being has no ability to sense your presence?"
