the animator probably requested that this be put in the script because they were so excited that the boulder came out as great as it did so he wanted a little reward for himself… at least, that’s what I would have done…
Maybe they had a ton of trouble rendering the boulder properly and so when it was done they were like ‘You know what? This shit deserves a line in the script.’
As the daughter of a renderer, I can confirm this is pretty likely. :P
