Sevtlana lives on a volcanic island out in the Mediterranean sea with her father, a research scientist at a top-secret facility that manufactures "Uncle Flubby's Puppy Grub" brand dog food.
According to Bondo's version of the Free Kid Database, Svetlana is a smart, curious girl who is in wonder of the world around her. Sevtlana was first seen on the FKD as Yakov's perfect person. Afterwards a brainwashed Yakov meets and is adopted by Sevtlana. Later she unknowingly gets Yakov back to normal.
