In one episode, it is revealed that Abby has some kind of a double personality, in which she was acting like a very nice and innocent cow, then the other second, she was acting like a strong, rough cow. She seems to be very competitive and very pushy and stubborn at times.

In the episode where her cousin Veronica visited and attracted Otis, Pip, Freddy, Peck, and Pig, Veronica said that she would take Otis back with her referring to him as "the big cute one", then Abby got really angry, and said that she has to take "Otis" out of her trance, then Bessy correcting her saying, "Don't you mean all of them?", then she did had an embarrassed-sounding laugh while saying, "Yeah, I mean them."
- Abby is a bottle blonde is it isn't her natural hair color.
