Just started watching this. Now for concentrated doses of autism.
Not sure how to explain this without sounding like a pretentious fedora, but this has to be one of the most philosophical and deepest cartoons.
If you look on the show normally you just see random shit and stuff the animators probably made on a whim, unless you interpret everything as a metaphor.

Xavier for instance is made out of random parts like a beak, snake arm, reversed legs and the like while going a quest to discover himself. You could interpret this as a metaphor for a person who is transforming. The parts represents different aspects of himself that has changed over the years, the experiences has made him what he is.

This is the most autistic post i have ever made but i seriously believe this show is smarter than it makes itself out to be.
