Back when the overworld was in its prime, a company called Fazbear Entertainment was the leading company in robotic and arcade entertainment. One of its more obscure redstone creations was named "Felix the Shark." He was an aquatic animatronic who would swim along with the guests. Though very few children were able to witness him in action. No one knows why he was discontinued and left to rot, but now they roam around the ocean monuments as if they finally have a purpose. It's a shame. They never knew any love until recently, and their first caretakers are psychos. Be careful, they may be a coal a dozen, but their newfound power makes them some of the most lethal beings in the water.
