There’s a chocolate bar i found that contains espresso, and its the only non-liquid food I’ve found that is genuinely strongly caffeinated. I think it was labeled something like “Nuts and Jolts”?

Edit: brand name is Chocolats Latour, flavor is Nuts & Joltz, description is “caramel walnut latte bar, 40% cocoa”.

I assure you, One Piece is very much not child friendly later on. The first like 700 episodes build up to a specific story arc (Wano). The current (anime) arc has a major back story of a characters life which includes him begging to be allowed to die as a child.

That and the anime pacing is terrible.
