Oblina comes from a wealthy monster family. She is shaped like a black and white, upside-down candy cane. Oblina is believed to be Gromble's best current student. One of her favorite methods of scaring humans is reaching within herself and pulling out her internal organs, and she has considerable talent for shapeshifting into various terrifying forms. She also has a talent for inducing nightmares in humans, by sticking her finger in their ear and tickling their brains while they sleep. Oblina is interested in reading and is very practical.
