Still haven’t heard a cohesive argument against Tama and Momo, since “They’re kids!” really doesn’t constitute a defense whatsoever. Already listed the (admittedly few) ways in which Tama could be useful on a ship, and as far as Momo, he should be much less of a sniveling asswipe by the end of this arc, and he’ll still have his quasi-Kaido DF powers as well as the Ame no Habakiri, so it’s also not beyond the realm of possibility that he could prove helpful in some ways. Don’t come at me like I’m saying they’re both guaranteed to join the crew because that’s obviously not what I’m doing, but if it’s not the age bias or personal distaste, I’m not seeing any good counterpoints for why they couldn’t be on the Thousand Sunny.
