Tad is a creature of short stature completely covered in turquoise hair, very similar to Kelly's, with eyes, a mouth, and two brown-skinned legs. This appearance causes him to blend into Kelly's hair. In "Lava Lake Beach", Tad is revealed to have at least two sets of arms.
Tad first appears near the end of "Goblin Dogs", having been camouflaged in his then-girlfriend Kelly's hair the entire time. While the rest of the characters sought after the Goblin Dogs, Tad states that he is a vegan and doesn't really eat hot dogs.
In "The Bounce Lounge", Kelly states that she and Tad broke up, and she joins the rest of the old Bounce Crew in saving the Bounce Lounge from being closed in order to get her mind off their breakup. Near the end of the episode, Tad and Kelly get back together.
In "Starcrushed", Tad and Kelly are stated to be on their third "break" of the week.
In "Lava Lake Beach", when Kelly decides she wants to break up with Tad for good, Tad drowns his sorrows in pizza and soda, and he refuses to move out of Kelly's hair. When Marco (whom Tad considers to be his best friend) talks to him and helps him move on, Tad subsequently helps Marco realize his true feelings for Star Butterfly.
