Oh, I remember that drum stuff. When Luffy mentioned that people never sleep in snowy countries? But here we have the same situation again. Both times, with Luffy and Buggy, they say they just heard it from other people. I swear who keeps telling these kids these stories? I wonder who specifically told Luffy and who told Buggy.
Luffy says he heard it in a tavern once. I assume one of the red-haired pirates told him that then?
Maybe I am making this stuff more complicated as it is.
