Mexican Jello Flavors

Just got back from the grocery store. The store I like going to has an entire aisle filled with strange foreign foods. From British to Asian to Brazillian to Mexican. I love wandering down this aisle and just looking at all the crazy stuff. The mexican jello flavors always stumps me, though. I mean, what's so appetizing about walnut, pistachio, or eggnog flavored gelatin? Although, I will admit, as scary as it sounds, the eggnog flavor smelled pretty damn good. But not good enough to actually buy. Maybe someday when I feel frisky and like I want to gamble 97 cents, I'll try it.
