Sometimes Petina can get fixated on something. Like Rosemary's tail. When she gets this fixation it can be become single focus of her world.
Also when you have such radically different sizes in individuals it can result in odd social circumstances. Like asking one your best friends to get out of your tail. Literally.
That is what happened in this series of sketches from several years ago. Petina decided to skip out on helping Jackie with some tax paperwork and instead decided to take dive into Rosemary's tail.
