Sounds like something you should try to see a vet about if possible. If the "orange stuff" is globby and solid intestines it might be a prolapse which could be life threatening. In that case you should keep it damp and maybe sprinkle sugar or drip honey water on it to make the swelling go down and get it to go back in.

If it's just liquid or slime I have no idea what that is but you should get it checked out. Any chance the frog ate one of those orange cricket food cubes?
