Betty considers herself a feminist, and wears a purple shirt with the symbol for "female" on it. Her big brother, Freddie, wears a shirt identical to hers but has the male symbol on it instead. In All Grown Up!, she works with Chas at the Java Lava Coffee House, and also helps Principal Pangborn with the school's soccer team, which Phil and Lil are a part of.
Despite their age difference, Betty really loves Howard. Betty met Howard when she finished college in 1982, and she immediately started dating him. They got married 5 years later, right after Stu and Didi's wedding, and they renewed their vows in 2001 in Runaround Susie.
Betty has peach skin, brown hair, pink lips and a pair of white eyes with black pupils. She wears green earrings, a purple-and-orange shirt with the female symbol on it, blue jeans, orange socks, blue and green sneakers and a blue headband. She has a very large build.
Betty has appeared in many episodes of Rugrats and All Grown Up!. Her first appearance was in Tommy Pickles and the Great White Thing. She goes on to make even more recurring appearances in the spin-off series All Grown Up!, running the coffee house with Chas.

- In the episode Mother's Day, it is revealed that she used to breastfeed Phil and Lil when they were under a year old, though, being that it aired on Nick, it could not explicitly be shown (i.e her shirt wasn't lifted).
- In the All Grown Up! episode TP+KF, she is shown to be a Halloween prankster, and disapproves of no fun.
- Betty was born in 1959, but she's older than Didi.
- Betty drives a blue 2-door 4x4 SUV in later episodes (after Rugrats in Paris: The Movie; seen in A Rugrats Kwanzaa) and continues to drive this vehicle in All Grown Up. It is a generic but has styling cues from a 1986-1991 Chevrolet K5 Blazer, a 1986-1990 Chevrolet S-10 Blazer, a 1987-1991 Ford Bronco, and a 1991-1993 Dodge Ramcharger. In All Grown Up, it resembles a 1969-1972 Chevrolet K5 Blazer, but has modern features like an alarm system.
