the bucket of mud thing wasn't trying to prove the downfall of monkey isalnd after gilbert, i new very well where it was from and when gilbert left, it was meant to prove that guybrush was dumb and ignorant in the first two. if you want proof of him being more dumb and ignorant in the second two, play the games and you'll see how. but agree with jake, this is getting increasingly dumb, so lets stop now before this gets really dumb (it has happened, you can't deny it)
Peace
