At the end of the first film, the narrator revealed that Robert got a personal trainer, lost a lot of weight and goes on to become Taylor Lautner.
After he was born, Donny promised to let him have anything he wants. Robert grew up as a spoiled child who always got everything and was quite grateful for this.
Robert does not return in the sequel. It is unknown what happened to him as he is never mentioned.
Robert is very spoiled, mean, arrogant, and greedy. He is almost as unhinged and mental as Donny: He hates it when he cannot get what he wants and would attack anyone who might upset him. Robert is also sheltered and gullible, willing to believe anything Ted told him so, as long as he said it politely.
At one point in the first film, Robert told Ted he once said a swear word and his father punished him for it by spanking him (or, as Robert calls it, "gave him an ouch"). He then told Ted he now has to give him "an ouch" and then proceeded to rip Ted's left ear off and throw it across the room as punishment for swearing.
- Robert is sometimes thought to be the tertiary antagonist of the first film.
- Due to his weight problem, Ted usually calls him "The Fat Kid."
