The penguin says slide. Meaning let go, relax. You can't control everything. Your condo doesn't need to be complete to be happy. Slide.

But Marla enters and the penguin can no longer help narrator. Without help, he evolves(I chose evolve instead of devolve) into Tyler.

It's my favorite film of all time. The themes of

-consumerism

- media

- mental health

- evolution through suffering

- and the futility of man. He avoids conformity but ends up creating a group of conformist who look the same and don't ask questions.
