"You don't like the name Red-eyed?"
"Chirp chirp!"
"You want to be called Kevin?"
"Chirp chirp!"
Without a doubt, Russell could confirm that the peculiar murmuring he had just heard originated from the Red-eyed Rat King.
The ability to listen to the private murmurs of Fantasy Beasts, brought about by the Extract of Clutch Berries, indeed existed.
However, there was a matter of probability, as it wasn't guaranteed that Russell could hear the Fantasy Beasts' whispers at any given time. As for when he could or couldn't, that required gradual exploration.
"Kevin is already taken, so you can't be called Kevin," Russell slowly said as he looked into the disappointed eyes of the Red-eyed Rat King. "But you can be called Jerry. Jerry is a household name, and it sounds even better than Kevin."
"Chirp chirp!" The Red-eyed Rat King nodded vigorously, clearly very fond of the name Jerry.
Of course.
