Awesome changes! I think this is the only day 6 build with a real sprite for bob. VERY COOL. I missed this one at first. Glad I found it. You really nailed the atmosphere, and as Ravendave said, the first bob encounter is much more frightening now, even to me after spending a while trying to get bob the fish into the game!
Nice job!! :)
EDIT: I just found the 4th version of this game and it also has a cool sprite. Didn't mean to discredit them.
EDIT 2: Would you mind telling me what you did with Bob's AI? I wasn't sure quite how to build it myself so I kind of used choo choo charles as my reference "behaviour."
