I think that a lot of things like this, as seen below, don't just occur in one person's head. They occur because two or more people were talking and an idea was voiced. That idea may have been mulled over, or adapted, but then eventually something was done with it.

I also forgot that pokemon need to be trained. <Insert Super Junior training jokes here>. I was just pleased that she came up with a Super Junior nerd crossover and then made a picture and posted it online. So here is her picture.
