How do you get past room 3 in the prison in daxter?

It's simple just get the key and run to the first room you see after finding the key and crawl under the prison bed.Once the crimson guard leaves immediatly crawl out and run to the next room. keep doing this until you find a hole under the bed.When you find the hole crawl in it and your out......for now. (p.s., if you keep failing then keep running once you get the key, just don't bump into any one of the Crimson guards.)
