Boris Kropotkin (born 1917) is the husband of Minka Kropotkin, the father of Didi Pickles and Ben Kropotkin, the father-in-law of Stu Pickles and Elaine Kropotkin, and the maternal grandfather of Tommy and Dil. He, like his long-time wife, comes from the "Old Country" (later revealed to be Russia). In "Passover", he mentions his wine glasses being from Smolensk, so it's possible that's the city he is originally from. Although he always talks about how terrible life was in the old country, Didi once revealed that he actually comes from a very well-off family. She then added, "he wouldn't know a goat if it bit him in the face." He frequently gets into petty arguments with Minka over various issues, such as who will turn on the television, and why chocolate cake should be used at birthday parties, instead of carrot cake. He is also a wonderful storyteller, as he will often tell vivid stories about "monsters". He and Grandpa Lou are a lot alike in storytelling, their overactive imaginations with their stories, and being romantic with their wives.
Boris is a very eccentric, yet interesting man who is able to tell great stories. He argues often with Minka and, occasionally, Lou. He usually rambles on about his past experiences living in "the old country".
Description
Boris is the grandfather of Tommy and Dil. As he tells Tommy in "Toys in the Attic", he found Minka to be the most beautiful girl in the village, and he adores her cooking. Being Jewish, Boris and Minka embrace their faith well, sharing their faith with their extended family, including Angelica, whom they also see as their own grandchild. This is very evident in "Chanukah"; when Boris sees Angelica crying, he carefully takes her from Schlomo and continues to hold and comfort her until she calms down.
It is also shown in "Toys In the Attic" that he and Minka keep all kinds of knick-knacks and antiques, most of which are broken by Tommy and Angelica. After which, he and Minka both faint, but later they hide all the antiques from the kids. He is seen in The Rugrats Movie, giving a goat for goat's milk to Didi when she is expecting Dil soon, and also helping Lou look after the babies when she goes into labor. He is seen in the beginning and end of Rugrats in Paris: The Movie, getting hit with cake by accident. Upon hearing Lou laugh at him, he starts a food fight by hitting him with cake.
Looks
Boris has fair skin, black dot eyes (with sclerae in later seasons), and a few hairs on his head. He is often shown wearing a green jacket and a white undershirt as well as blue jeans.
In the first three seasons of Rugrats and up to the Rugrats Passover special, Boris was shown to have dot black eyes. However, starting with Chanukah, he was shown to have white sclerae, and would be in the fourth season of Rugrats onwards, the films, and in all three of his appearances in All Grown Up!.
