Jen and Smilecat are Rule 63/opposite versions of Jeff and Smiledog. Jenna shares the same characteristics as Jeff. She can run quite fast, but isn't really strong. She enjoys sneaking up on her victims, especially when they're sleeping. Jen carries a large knife in the pocket of her hoodie which she nicknamed "Sir Stabbington". She enjoys using different creative ways when she kills people. She is always seen wearing a white hoodie, black dress pants, and black boots. Jen has a loyal companion named Smilecat, or Smile. Smilecat isn't as scary as Smiledog, but she can be a bit creepy sometimes. Smilecat is a bit smaller than Smiledog. Her "original" self appears to be a dark gray cat with bronze-yellow eyes and similar tabby marks on the forehead, paws, and tail.
