Stuart Louis "Stu" Pickles Jr. is the father of Tommy and Dil, also the younger brother of Drew Pickles, and the husband of Didi Pickles and the second son of Lou and Trixie Pickles and the son-in law of Boris and Minka Kropotkin and the uncle of Angelica Pickles. He is described as an absent-minded toy inventor. The inspiration for this occupation is his infant son, whom he thought would enjoy playing with new toys created by his father. However, malfunctions usually occur with his inventions, and when his inventions do not malfunction, they scare the kids. Stu is a fun filled kid in an adult body. His favorite pastime is inventing.
Aside From Inventing
Aside from inventing and playing with his sons, he's mostly seen arguing with his older brother Drew. Drew and Didi tend to scold him for not getting a more dependable job to help support his family. Stu doesn't seem to like manual labor; when he once got a job selling lard, he showed great disdain for it. Like the others, Stu tires of his father's overexaggerated stories. Stu loves his family dearly, and goes to many lengths to keep them happy, even at his own expense. Sometimes he does the unnesscary to get people to like him.
As a Baby
It is shown in the episode "Sour Pickles" that like his son after him, Stu secretly had a screwdriver to unlock his and Drew's crib, and that he wore a shirt and a diaper only (similar to what his son wears in the present time).
As a Adult
As an adult, Stu was voiced by the late Jack Riley, while as a baby, he is voiced by E.G. Daily (who also did the voice of his son in the present time).
- In the original pilot, Stu's name is Stu Pickles, Jr.
