How to rotate animation in unity?

Question

Unity

I downloaded a free spider-man animation from mixamo.com. I want to make it able to crawl on walls, but in its current state, it seems to be crawling on the floor. And so to a question: How to rotate animation in unity? I tried to just rotate the object itself, but in my case it's not an option. He is tied to a camera that monitors the character (too many crutches). Suggest your solutions
