Gorilla a character who appeared in I Had an Accident. He showed up out of nowhere, disguised as Patrick, and stuffed the real Patrick and Sandy into a bag, smacked them on the ground ,and stomped on them, causing SpongeBob finally go outside. He also hangs out with George the Zebra. When SpongeBob asked what the gorilla was doing underwater in the first place, the gorilla panicked and fled on George before they could question him any further, leaving everybody confused. He is voiced by Frank Welker. The Gorilla also appeared in the episode Friend or Foe? in the Patchy segment, as Patchy's replacement. He is apparently a better cook than Patchy.
The Gorilla is very big and looked very much like a costume. He was fluffy and the man who played him can be seen through the costume's eye holes.
