Sounds like fuzzy is about to shed. I always bump my humidity up to 70-75% to help with the shed. First noticeable change is generally a pinking of the ventral scales. Then you will notice he/she will become dull in color and eyes will start to go blue(this is called in blue). The eyes will then clear up and usually within 48-72hours after the eyes clear they will start to roll out of the old skin much like rolling a sock down. Some snakes will soak more during the shedding process especially if the humidity is too low.
