In "Robo Frog 3000", Slips sat at the table, telling a story about his father to his friends. He was heard saying "Then father said, 'Way to go, son. You're a man now'", before a giant robot destroyed their table, interrupting the story.
In "Lyon's Anatomy", Slips told another story about his father at the same lunch table. This time he was head saying "Then father laughed and said, 'Snakes don't wear shoes, son.'" His story was interrupted again, when Nurse Gazelle showed up.
In "Where in the World Are Adam's Parents?", Slips' parents made their first on-screen appearance, though it was brief and they did not speak. They both accompanied him to the Student of the Year Awards. When Windsor and Jake wondered where Adam's parents were, Jake suggested they never showed up because they didn't want to embarrass him. Slips then said "That doesn't ours away", implying that his parents embarrass him.
Slips' mother is a long snake whose skin is the same shade of green as her son's. She has long, brown hair, eyelashes, red lipstick, and breasts. She wears a pink dress that doesn't have arm holes. Slips' father is slightly shorter than his wife, and has a lot darker of a skin tone. He has black hair and a blue suit, along with a white shirt and black tie.
