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. Throwing another tantrum, he convinces his father and Butler to buy Pluto from Mickey.
After his father buys Pluto from Mickey, Adelbert seems to finally calm down. However before very long, he tortures, harasses and treats Pluto badly, tying food and other items onto his tail and pelting him around the house, sending Pluto into a panic. He then starts to throw expensive items, toys and food at his father and the Butler. The father tries to stop him but is unable to calm his son down, and the mansion soon becomes a ransacked mess. Adelbert then launches Pluto from the Christmas tree, ruining it and causing further injury to his father. Finally, unable to take it anymore, the father, having 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. Adelbert immediately throws another tantrum demanding Pluto, but the father refuses to hear any more of it. 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.
