Grrrr is the name given to one of the protagonists of the Pirate S.T.C. series. Her name is likely not actually "Grrrr", but is the sound she made when asked her name by Fezhead.
History
Grrr was first seen surfing the channels along with Sackhead, Flame, Bob and Dog the Chicken. She was responsible for switching the channel from Bulldog & Bulldog to the Y Not Y-Fronts Man and claimed he was a hunk, although she was left confused when he was replaced by Skull. Before she could watch any more commercials, she was sucked into her own television. Once there, she angrily defied Fezhead when asked for her name and was quickly spat into the Mouth of the Mission. Along with Bob, Grrrr was dropped into the woodland area and accidentally turned some of its inhabitants into bubble bath containers.
Grrr immediately leapt into action, protecting the rest of the creatures from being struck by Granee 8 Ball's projectiles. Her next job was to fight the Kamikaze Whippysnappers and was initially successful, performing acrobatic moves to defend herself. Unfortunately, she grew over-confident and was soon submerged in the second wave of ice cream. Both Grrrr and Bob became by-standers for the rest of the "game", watching as their friends made their way to the level, followed by the Y Not Y-Fronts Man's convoy. She eventually made her escape when carrot-launching pigs began to eat the ice cream. After being subjected to love spray, Grrrr was taken to the next level by Fezhead.
