It is by far the greatest D&D adventure of all time.
Right you are, rip! As you've already described, the plot is inspired. The adventure (which has a map consisting of 2 corridors and 2 rooms) is also particularly great because of the new material it contributes to the game.
New monsters presented include hot mustard jelly, olive and pimento slime, crystal lite ooze (is there a trademark violation there?), and chocolate fudge pudding.
It also contributes significant new background material on Juiblex himself... including such gems as how "as a boy, Juiblex was teased and taunted by the other young demons who used to laugh and call him names (Scum Face or Barf Breath being the most popular). They never let poor Juiblex join in any demonic games." It also presents a fairly detailed description of Juiblex's talisman ("a small glass jar that once contained catfish bait and now contains his vital essence").
Its not like the normally thorough Ed, James and Erik to mess up like that, but they seem to have accidentally left all of that important canonical material out of the Fiendish Codex I!!! Shameful!!! I'm very disappointed in them. It was highly unprofessional.
