Applying Propp's Narrative functions of a Fairytale to 'Finding Nemo'

Brief Synopsis
The clownfishes Marlin & Coral move into a new home but she and all but 1 of her eggs get eaten by a barracuda. Marlin names it Nemo as suggested by Coral. Some time later is Nemo’s 1st day at school and he gets annoyed and embarrassed by Marlin. Disobeying him, Nemo swims out to open water and gets caught by a scuba diver. Marlin chases after him but can’t catch up. On the way he meets Dory who has short term memory loss. Dory helps Marlin try to find Nemo and on their adventure they meet sharks, an angler fish, a school of fish, jellyfish, sea turtles called crush and squirt, a pelican called Nigel and also a whale who takes them to Sydney which is where Nemo is. This all goes on while Nemo is in a fish tank in a dentist’s making new friends who help him try to escape using various different methods, they have a time limit though as a little girl called Darla wants to take Nemo home to kill him. In the end Marlin and Dory find Nemo and Marlin reconciles with Nemo and apologizes for being overprotective. Once they have returned home, Marlin is able to let Nemo "go have an adventure" at school with his classmates, including the new exchange student, Squirt. The 3 sharks bring Dory home from a Fish-Eaters Anonymous meeting. The fish in the dentist's office make their escape, having followed their earlier plan of breaking the filter and rolling out the window, across the street, and into the harbor, leaving them with the dilemma of how to escape their plastic bags.

Critique of Propp - Here are the main functions that do not fit with the story:
There is not really any magical object or any kind of magic in the story.
Hero doesnt marry and ascend throne.
Hero is not given new appearance (but he does think differently about his overprotectiveness).
There isn't really a true and false hero - Nemo has his heroic moments but Marlin is the main hero.
