Karley on Day 617

Karley is Mallory's younger sister who appears on the vlog whenever Stephen takes a trip to Wisconsin. She has a boyfriend named Kyle. She has taken over the vlog as "KarleyVlog" twice. She currently lives in Minnesota with her cat named Ted. She is well known on the vlog for her random style of humor and outgoing personality, such as when she rubbed Stephen's toe, mistaking it for Mallory's. Despite her insane humor, she is actually a science teacher, and she studied physics and astrophysics in college. She is a common fan favorite of the vlog.
