They are mentioned numerous times, throughout Season 4 by Hollyhock.
They make their first appearance in Lovin that cali lifestyle!!, when they travel to L.A. after Hollyhock accidentally overdosed on amphetamines, which unbeknownst to anyone at the time was due to Beatrice putting weight loss supplements in her coffee.
They blame BoJack and refuse to ever let him see her again.
In What Time Is It Right Now, BoJack travels to their home in Wichita, Kansas, and after begging them to hear him out, he explains how he discovered he isn’t actually Hollyhock’s biological father—his father Butterscotch is.
