if we were to examine fake peppino, you would see that his pants are a part of his body. meaning he has no genitals. so procreation would be impossible since two genitals are needed for breeding.

could he give sloppy toppy? most definitely, but it is not reccomended due to him being quite hostile.

and also, fake peppino can not speak for himself.
meaning fake peppino cannot give consent, making it morally wrong to even attempt to breed him.
