"Sorry, babe, but the pink catsuit-pants..."

...and cherry-red plastic booties just ain't doing it for me, if ya know what I mean.

Why on earth did the "deciderers" on this film choose such an outlandishly silly "jungle explorer" clown costume for the lovely Ms. St. John? Especially when there were plenty of better and more-plasuible (within the context of the genre, that is) ways to gratuitously show off the lady's attributes. For instance, after the Scooby gang gets captured by the natives and preparations made to sacrifice them to the volcano gods, just have the locals separate out the lady and say something to the effect of "she become one of us". (They could just alter Vitina Marcus' "Native Girl" character to speak a smattering of English and help explain, or bring out the old blind lifer from the previous expedition to provide translation services.)

Then the local ladies take Jill aside and dress her up right and proper, "short-skirted and strategically tatter-garmented jungle goddess"-style, like Native Girl, and voila! You get your eye candy - times 2, since Vitina was a major hottie in her own right - you maintain a veneer of plausibility, and you give the fellas a chance to be heroic and rescue both Jill, erm, I mean Jennifer, and Vitina, ehm, I mean Native Girl. And you get to put the "No ridiculously brightly-colored plastic clothing items were harmed during the making of this film" seal of approval on the whole affair. What's not to like?

Or, if you must have a bit of camel toe, why not use khaki-colored jump-pants? And you could still do the jungle-girl dressup bit later on. Sheesh...
