So, what is Bloody Gir? 

Bloody GIR's a top secret easter egg character that nickelodeon doesn't know about

Since NICK wouldn't let JV put blood in his cartoon,he ask someone to draw GIR covered in blood and put it in the show for him.BG(Bloody GIR) is an easter egg that is in 1 or 2 frames in the show.After the episode bad,bad rubber piggie,there where many other BGs in the rest of the episodes in the show.So far there are 7 found,so there are another 7 to be found.BG wasn't the reason the show was cancled.NICK found out about BG AFTER the show was cancled.To this day,people crop,pause,and look carfully to find all the other BGs.

A Bloody Gir is Gir covered in blood and can be seen in most episodes. but they are hard to find. one of the locations is from mortos der soulstealer right before the sequence of dib come out.
