idk??
i had the idea that maybe Voodoo, in his spare time, mixes up a kind of 'vore potion' with all his Witchdoctor-y magic and whatnot
Its effects would be something like

-invulnerability to digestive fluids
-heightened sensitivity
-increased sexual satisfaction
-no-light vision

so basically you drink it and you can be vored without fear of being digested! uwu but that means you'll have to come out one way or another
