Finding Nemo has two stories in it. The larger story is the title's namesake "Finding Nemo" and can be found as a storyform here. In that story Marlin, Nemo's father, is the Main Character, with Dory (and a bit of Nemo) as the Influence Character(s). The smaller story takes place in the Dentist's aquarium. In that substory, Nemo is the Main Character and Gill is the Influence Character. The substory isn't as specific as the main story, so it's tough to get a single storyform, but we were able to identify parts of it:
