Strange Japanese "Dessert" ... real?

[dknightx]

I was talking to a good friend of mine, and he told me that one of HIS close friends (we will call him Bob) recently went on a trip to Japan. Bob said that in Japan, there are these restaurants, that have this "special dessert" that you have to call in a order a few weeks ahead of time.

In white (if you really want to know):

Anyways, the dessert is basically a girl's poop. Yes, POOP. But here's the thing, when you call in and order the dessert, you say what FLAVOR you want, so say you want apple flavor, they will have the girl eat apples for like a week straight.

When I heard this, I basically said "There is no [censored] way this is possible" (especially the whole "flavor" thing) ..... BUT knowing the Japanese, there is some strange/unimaginable stuff that goes on over there. Anyone else hear of this before that confirm whether this is true or not? My friend seems to be convinced that it is true.
