They are voiced by Becky J. Johnson and Rachel Jones.
Capicola and Pancetta are abusive, cruel bullies who may seem pleasant at first, but take great pride in bullying, torturing and abusing their younger brother Salami, thus giving him PTSD in the process. They have done stuff like take his toys, pull his hair, eat his snack, and mock his strength. They continue to do this well into adulthood, as demonstrated in Meet the Strongs. However, when Salami finally stands up to them and calls them out for their ruthless behavior, they apologize and make up with him. Salami says that stuff like this happens all the time and they always apologize, but it's implied that the abuse cycle will continue later on.
They are named after deli meats just like their younger brother and mother.
