If it goes according to the typical 50s-"exotic" B-movie formula, or, by extension (wince), the Troma Pictures soft-porn-formula, then there will be a Very Important Sacrifice Ritual - before which, of course, it is absolutely necessary to have a poorly-choreographed cheesecake dance. Why? I don't know. Maybe it heats up the volcano. (or, more likely, the director…)
PWGR2000 -- the ultimate collector of vintage cheesecake dances on YouTube -- has numerous examples. Here's a typical one:

Just before the sacrifice, Margaret will throw herself upon Luffy, saving him from being burnt, impaled, beheaded, squished, bit, drowned, whatever. And for this act of disobedience she'll be expelled forcefully (with much hair-pulling and clothes ripping) from her tribe. Due to her disobedience, the Very Important Sacrifice Ritual is never completed, so the island suffers instantaneous bad-karma: volcanoes erupt; rival tribes (all male, how convenient!) invade; gigantic animals slither out from the jungle; etc. But our resourceful hero and heroine make a raft out of downed coconut trees and sail off into the sunset together …
Now all we need is Joel (or Mike) and the 'Bots to appear at the bottom of each manga frame and heckle it as it unfolds.
It's an amusing development, but I still stand by my opinion (from the spoiler thread) that the timing is off.
It's too soon to be silly. Too much silliness too soon cheapens the sad chapter that came before.
