Don’t know why but I feel Unclenapped Buggy would probably get along very well with Brook. Most of it is just because I fucking love the idea of the two possibly weirdest (Altough that’s saying something) crewmembers hanging out watching the daily on board chaos unfold all while Buggy just grumbles something like “God those idiots. I’m so glad we are the only two normal ones here.” “Yohoho! Oh, you flatter me.”, but also just… I don’t know I feel like those two would vibe well.
Oh the comedy potential here!
Because I imagine Buggy is a little calm that both Robin and Franky are almost middle aged, so he won't feel as old. Still, he feels like he's the only adult, only he gets back pains and complains about the weather, only he has the uncle vibe... But then Brook - a literal skeleton (that's how old he is) comes along, it's an instant bond.
They're making dad jokes and complaining about cramps all day long. Buggy is the only one who laughs at Brook's jokes. And most of the time they just lounge on the deck in the sun. Not even napping, just sun bathing. Both of them love it so much because both of them were deprived of any sunlight for decades.
When Brook had a whole thing with Laboon - missing the only friend still alive, Buggy felt it so deeply. He's not sure why. He doesn't remember having friends but it would have been nice to jave someone still waiting for him, wouldn't it?
He's mainly happy he could have friends anymore.
