It happened in Ranma Movie 2 (the dub at least.)
When the girls started disappearing, Genma (of course) told
Ryouga: "Didn't you know that these seas are filled with evil, man-eating
octopi?" (or words to that effect.) Ryouga predicatably panics over a
similar fate happening to Akane, and when the next girl disappears, Genma
stoically pronounces "Curse those evil octopi."
In the sub, don't they say something like 'The kidnapper is a GHOST!!!'?
That hardly narrows it down, Kun-chan. There are heaps of different subs
around.
Kun-chan @baps Martin over the head.
Look!
It happened in Ranma Movie 2 (the dub at least.)
And there's only one sub of the second Ranma Movie in Melbourne that I
know about! That one where the sound is stuffed right at the end, and
where they call Happousai 'Happozai' and where they translate 'Muko-dono'
as 'Wake up'!
