Ranger Marsh is a park ranger in the Everglades in Florida, USA. He is Tweak's dad, but doesn't know how or why his daughter Tweak builds the machinery she does, which he calls gadgets and gizmos. The only piece of technology that he has is a very old radio that doesn't work well most of the time (he was given a tablet so he can talk to his daughter whenever he wants, but is shown holding it upside down and messing up with the volume). He always does things the "Old School" way, like using his smarts and bare paws.
