Role in the short
Adelbert is first seen crying, throwing temper tantrums and refusing all the expensive toys that his father and the Butler have been trying to give him. Then, upon hearing Pluto's howling, Adelbert walks over to the window and peers outside. Upon seeing Pluto, Adelbert decides he wants a dog.
After his father buys Pluto from Mickey, Adelbert soon tortures, harasses and treats Pluto badly, and throws expensive items, toys and foods at Pluto, his father and the butler. Finally, unable to take it anymore, the father, believing he has had enough of Adelbert's vandalism and cruelty to Pluto, tells the Butler to throw Pluto out the front door (along with a turkey that his son tied to Pluto's tail), and the Butler does. Finally, his father drags his son onto his knee, pulls his pants down and spanks him for not treating Pluto right and ruining their home, much to Pluto's delight.
- It is very unlikely for him to be considered a villain because he is only a kid and has to be educated. He can, however, be considered a bully or simply an antagonist.
