The whole peach bit is obviously a reference to Momotaro and probably should be tagged but the tag momotaro is blank, which doesn't seem likely considering how often I've seen it referenced or parodied before.
I think it's like a Japanese version of the stork, or any other story parents tell young children to explain where babies come from.
