Three chapters in the same flight-from-Totto-Land sequence reuse one fixed grammar for the chapter-closing beat, and all three land on page 17: giant Big Mom (or her proxy) packed into the upper register, the same fleeing Sunny at bottom-center, a “DOOM” sound effect, and a cake-demand line. The vehicle of the threat escalates each time — she rides Zeus (0873) → she becomes the wave itself (0880) → she rises whole from the sea under her own power (0887) — telegraphing a mounting, inescapable pursuit. When hunting the rest of this arc, the page-17 “DOOM + looming Big Mom over a speck-ship” template is the cliffhanger tell to watch for; the iteration that finally breaks the template (the ship escapes the frame, or Big Mom is the one dwarfed) marks the pursuit’s turn.
