My Pacman Frogs

I'm not sure about the clicking noise, but the color change is fine and normal as they grow.
Cranwelli tend to change dramatically in color as they get older. For instance your new green one there will probably lose it's green and tend brown by adulthood. Every once in a while there will be a green cranwelli that will stay green it's whole life, those are exceptional specimens.

Appa hasn't made the clicking noise yet again, but today Gary was making a really loud noise that sounded like a mouse being killed. Is that normal?

Also, does that mean it's a boy or do females make noise as well?
