what is wrong with my iguana?

  my iguana has like a gooeyy brown stuff in his right eye and it is really starting to scare me cause he has been fine up until friday night. i am scared that something is wrong he eats fine and everything. he was shedding and still is a little bit, but he is really moody all of a sudden
You should to take him to see a vet. if u read the care sheet, it would say an unhealthy sign of an iguana is leaking in the eye. take him to the vet!
