Story
Blip wrestled for years with his psychic abilities. He was shunned as a child by the other fish who hated him for being able to tell when they were hungry. Then one day, Blip got a bad feeling about a certain area of the tank. He didn't tell anyone, though, because everyone was mean to him. After all the other fish were killed, Blip felt guilty and vowed to only use his powers for good.
