Brook would have laughed out loud (and likely sprayed bits of food in doing so) to hear that he was being compared with a child the same age as the one in front of him. He'd been called worse, but it amused him when people made comparisons like that.

Instead he gulped down his first bite of food and with an empty mouth complimented, "That's such a lovely name, Ururu-san! Someone with such a pretty name shouldn't be looking so sad though! Yohoho! At least not so early in the morning!"
