I simply couldn't help but laugh to see that one of the beasties on the list simply has been called "The Cheap Monster." Isn't it quite obvious that it's cheap??

However, I wonder a little why the monster from The Bog isn't there. I mean, it looked so goofy that they actually did their best to show as little of the monster as possible!!
By the way, this list has inspired me to make a "Weirdest Alien In Sci-Fi" thread when I've collected enough nominations for my "Most Overrated Fantasy Author" poll and made that poll.
