Fredrick is a silver vintage computer. He has a black screen with yellow-green eyes and a yellow-green monocle covering his left eye. He also has a yellow-green nose and mouth.
His interests and hobbies include drinking virtual cups of English tea and saying, "I disapprove of this."
He is shown to love his daughter and disapproves of Karen's marriage to Plankton, much like his wife, E.M.I.L.P.. He also thinks she could have done better instead of settling with him and be with a more successful partner.
- He was created by a fan and then redrawn by the show's animators to the style of SpongeBob SquarePants.
