Nah, some grandparents just call their grandsons "son" or "sonny". In reality, Cranky has always been the grandfather of the current DK.
Here's my headcanon for the original DK game:
Mario (Jumpman) was a crazy 8-year-old kid who had adopted Cranky (DK) as his pet gorilla. Cranky is over 50 and already has a son at this point, despite Mario's young age. He treated Cranky badly simply because he was young and didn't know any better. He always dreamed of being a carpenter, even though he eventually decided against it. Cranky was tired of Mario's insanity, got cranky (pun intended), and captured Mario's closest friend, Pauline (Lady).
Soon after, Mario put a stop to Cranky's madness, and punished him for his actions. He had a very cruel and unusual form of punishment. So when Cranky's son came and tried to help him...Mario was trying to electrocute him. Poor guy. Anyway, DK Jr. eventually saved Cranky, and the two of them soon ran away from Mario's torture. They eventually met Stanley, but that's a different story entirely.
Before long DK Jr. had a son of his own. This Kong was named DK III, the current DK. Mario and Pauline were about 17 at this point. And by the time Mario turned 26, DK was an adult with a girlfriend (
Candy Kong) and a loyal adventure buddy (
Diddy Kong). Cranky is now 70, DK Jr. is now 50, and DK III is now 30. DK Jr. is still out there, hanging out with Toadsworth, Cackletta, Fawful, and Lubba in "The Room of Forgotten Characters".
