About the Screen Bug
It took place late 2006 (August-October) All I know is that it was supposed to be a new mascot. He was a Frankenstein mixed with Old Man Jenkins from SpongeBob SquarePants. He would walk across the bottom of the show that is currently playing and he would interact with the screenbug sometimes the screening would be white.
During a unknown episode of SpongeBob. SpongeBob was mopping the floor at the Krusty Krab and the person slipped and fall and he screamed very loud for help and a ident is shown that has that person dancing on Coach Street (The neighborhood where SpongeBob, Patrick and Squidward lived).
