Linda the Lungfish is one of the characters in Psychonauts. She is originally a boss character, who is fought underwater in a giant bubble, but after it is discovered that she was under brain control, she becomes a friend.
Linda is characterized by her huge, hulking appearance, and her incredibly husky and manly voice. She helps Raz by carrying him across Lake Oblangata, back and forth between the camp and Thorney Towers. She gives him a special fish-shaped horn to blow whenever he needs her assistance. After reaching rank 100 in the game, a bonus scene is unlocked in which Linda is shown to have a previous relationship with Mr Pokeylope, who is revealed to be named Sam.
