During the early storyboard and animatic development, the giant creature had less character: he originally did not comfort the berry before eating him and just walked away towards another bush after doing so. After some feedback, it was said to possibly raise a question in the audience of leaving things unresolved. In the final version, it was altered so that the berry’s unhappiness was resolved: the creature would pat him on the head to comfort him until the berry smiled again.
Additionally, the final scenes also changed: instead of eating the berry right away after being comforted and having the creature looking around for its next victim, the creature would throw the berry in his hand with a lack of interest and then notice something in the distance: another bush with another sad berry. He will then finish the “job” by eating the berry but not without making the audience hear the berry’s scream one last time.
Finally, instead of seeing the creature walk towards the other bush, we will hear his footsteps fading away to suggest that he is going to his next meal in the credits. These additional scenes are to give the audience a better view on the relationship of the two creatures and to make them think: “oh, maybe he isn’t going to eat him after all” while also making the final scenes seem like less of a rush of things happening all at once.
In the scene where the creature first tries to eat the berry, there is an added scene in the final version where we see the berry being brought to the creature mouth from the perspective of inside the giant’s mouth. This is to make the scene feel more gruesome for the berry and the audience.
