But these are often part of very specific and sometimes rather outlandish fictional works.

There are no real 'monster cock geowth stories' in the normal context. But if you are thinking about growth in terms of a made - up or fictional concept related to a monster - like creature, we could look at some role - playing games where players develop their 'creature' characters over time.
