Joy first appears in "Lincoln Loud: Girl Guru", where Papa Wheelie tries to impress her by putting a frog in her hair. This only angers her and prompts her to chase him down, alongside her friends, to beat him up. She then appears with Kat, walking down the hallway planning to beat up Lincoln and Clyde the next time they see them.
While she didn't appear physically in "The Waiting Game", her name was called by Chandler as one of the last two invitees to his birthday party.
Joy is a short dark-skinned girl. She has black hair, with some strands of her hair tied into two pigtails. She wears a lavender long sleeved shirt, with a purple necktie, a purple skirt, lavender socks, and purple slip-ons.
