I know I'm late on answering this but genuinely? The fact that they included Oswald is something that already amazes me! Plus Ortensia, her dad, mechanical cow and Fanny? That is already incredible to me so I see that as more of a celebration this time. (But yeah Clif as a crewmate would be perfect)
And you're absolutely right about the voice! It feels pretty spot on and, even better, it feels like Oswald being himself, like his casual goof self and I love how silly it is, AND NOT TO MENTION THE OUTFIT DESIGNS–
