Grandpa Lou Pickles, Tommy's paternal grandfather,is the classic, cantankerous, old geezer. He lives with his new wife Lulu at a retirement home, but often acts as a convenient baby-sitter for the babies when Stu and Didi are busy. Grandpa is indulgent with the kids. As such, he is almost more of a "Rugrat" than an adult -- functioning as a bridge between the world of kids and the world of the grown-ups. As much as the Rugrats love the old guy, they are never above taking advantage of one of Grandpa's long naps or mesmerizing television marathons to sneak away on an adventure. - Rugrats Description from Klasky Csupo
Grandpa Lou Pickles is still alive and kicking! Not only that, but he drives the school bus that gets Tommy and his pals to school every day. His hearing may not be what it used to, and he may be a bit slower and more wrinkled, but Grandpa Lou still remains active and energetic for a senior as old as he is. Too bad we haven't seen his wife Lulu yet in the All Grown Up series, but the last we heard (from Lou himself) was that she was traveling around the world! - All Grown Up! Description from Klasky Csupo
Being the elder patriarch of the Pickles family, and young at heart, he likes to be adventurous. Occasionally, he flirts with women. He is commonly thought of as having a wild imagination from the many stories he tells of his earlier years. In these stories, the number 15 is prevalent in various ways. Whenever Lou appears, his usual routine is to fall asleep in the middle of telling the kids a story. He loves his grandchildren deeply, and always enjoys spending time with Tommy and the others.
He shares a rivalry with his cousin, Miriam, but besides his rivalry with Miriam, he's had several other rivals. His bowling rival was Billy "Strike" Maxwell (seen in King Ten Pin), however, Lou later regains his honor by beating him after it's revealed that Maxwell was cheating the entire time. He also has a recurring rival with Conan McNulty, with Conan often lying to him and cheating.
When his wife Trixie has to go out of town, Lou takes care of his sons and grandchildren, and while he loves his sons, he has a great frustration with their constant bickering. Over the years, Lou has had many jobs, including a solider in the war, a cook, a repairman for small appliances, and a detective. Lou is also a bit of a schemer. He has quite a talent for playing the trumpet, as he was given a solo for the war veterans concert in Grandpa's Teeth. One of the things he loves to do is fishing and mostly watching TV, he's almost always seen watching a show involving fishing. While Lou enjoys doing new things, he can be very stubborn with trying some new things. He frequently compares the modern day world to the way it was in his day, often bragging on that the way something is done is nothing compared to how he did it when he was younger. He is, however, often thought to be making these stories up.
Lou Pickles has peach skin and a pair of white eyes with black pupils. He has gray hair and is often shown wearing a purple shirt and a green vest. He looked just like his son, Drew Pickles, when he was younger, but as he got older, he now looks more like his other son, Stuart Pickles.
Lou Pickles has appeared in many episodes of Rugrats and All Grown Up!. His first appearance in Rugrats was Tommy Pickles and the Great White Thing, while his last appearance was in the All Grown Up! episode Golden Boy.
- Lou often talks about his brother, Sparky Pickles.
- In Aunt Miriam, Lou states that he is actually 76 years old, meaning he could have been born in 1916. Lou's real age is unknown, since he stated in the episode Chuckie Gets Skunked, that he recalled a childhood memory with his brother Sparky back in 1906, meaning he was alive before 1916.
- In the pilot episode, Tommy Pickles and the Great White Thing, Lou is called "Stu Pickles Sr." in the credits.
- In Aunt Miriam, Miriam remembers that she and Lou had two friends named Bill and Jill when they were kids. In Potty-Training Spike, Phil and Lil mention having an aunt and uncle named Bill (uncle) and Jill (aunt).

- He claims he had to walk 15 miles everywhere when he was younger.
- He drives a green 1970s wood-paneled station wagon that resembles a 1971-1974 Ford Country Squire. In Submarine, he claims to have owned it since Stu was 15 years old and more than likely bought it new. Stu was born in late 1958, which would make the station wagon a 1973 or 1974 model. Lou's car has a vanity license plate that says "OLDTIMR," which means "Old Timer."
