Cheddarhead Charlie and Camembert Kate

Chedderhead Charlie and Camembert Kate are Monterey Jack's parents. Cheddarhead is an adventurer in his own right. Cheddarhead loves to travel, going on trips every year and twice on a leap year while Camembert loves adventures and travels more than Cheddarhead. She sometimes visited Monty and the Rescue Rangers. Camembert appeared in the episodes: "Parental Discretion Retired" (#08) and "A Lean on the Property" while Cheddarhead only appeared in "Parental Discretion Retired".

Cheddarhead
Cheddarhead is a mouse the same size and brown color of Monty. They also share the same nose and green eyes (though in one scene he appears to have blue eyes). He has chin-length grey hair, a grey bristly mustache, and appears to have some slight stubble. He wears a black Australian bush hat with a grey band, a long-sleeve red shirt, khaki vest, and purple fingerless gloves. He is sometimes shown with his sailor's duffle bag, which presumably contains all his possessions.

Personality
Cheddarhead is much like Monty, though to a further extreme. He is strong, loud, always ready to fight, enjoys adventures, is reckless, and prefers to jump in to a situation without planning first. While Monty has apparently learned the value of teamwork, planning, and caution during his time with the Rangers, Cheddarhead prefers to dive straight in to a situation, trusting his luck and strength to carry him through. It is unknown if Cheddarhead has cheese attacks like Monty. However, he has a slight reaction when he first sees Gadget, presumably indicating some level of attraction. His catchphrase is "Cheddarhead Charlie's my name. Adventure's my game."

Role
Cheddarhead joins the Rangers on a case. While his actions do move the case forward, he also charges in without forethought. This often results in trouble and danger for him and the other Rangers. At the end of the adventure, he admits that the Rangers' methods work, but they are not his style and so he departs. Episodes Charlie appeared in a single episode, Parental Discretion Retired.

Trivia

 * Cheddarhead apparently had not met Zipper before, or at least did not recognize him, implying that Monty and Cheddarhead had not met since Monty teamed up with Zipper.
 * The episode does not explain the relationship between Cheddarhead and Camembert Kate, Monty's mother. This is examined in some fan fiction.
 * In this early episode, Peter Cullen played Monty and Jim Cummings played Charlie. This is a possible basis for a retcon of the change from Cullen to Cummings for Monty's voice: his voice changed as he aged.
