Iggy has been a nature lover since childhood,[1] and has created a fictional worldwide organization dubbed the "Pig Rangers".
These are a special type of forest ranger devoted to learning about and taking exceptional care of the global environment.
A special gadget he possesses for his job is "Old Rusty", a one-of-a-kind pig-scout pocket device which contains many trinkets inside (e.g., a lemon grater, an eagle-calling whistle, and a boat motor).
Iggy is generally portrayed as an active, adventurous, out-going young pig, who is willing to take big risks to stand up for what he believes in.
For instance, in "If Pigs Could Fly", after taking in an orphaned condor egg, and raising the newly hatched chick, he constantly frets over her well-being (worrying if she's eating enough, getting the right exercise, might confuse Iggy, Jiggers or Zoop as her parents instead of the condor puppet Jiggers made to guide her with, etc.)
Jiggers is a beaver, who wears blue overalls with a light-blue grid pattern, and a red baseball-style cap backwards.
He and Kira have sometimes glanced at each other in an arguably dreamy way, and say complimentary things about each other, such as in "Yawny Come Lately", "Any Friend of Yours", and "Tower of Beaver".
He is the only official "Pig Ranger" other than Iggy (though Catfish Stu temporarily became one in "The Things We do for Mud"), and is also a skilled mechanic and wood sculptor.
He prides himself on his teeth, which play a major part in his work, and does his best to take care of them even ordering in an electrical toothbrush, called the Incisor 3000 with extra gadgets in "Mooseknuckle Unplugged".
[11] Although his allergy to ragweed has proven much more severe as he reacted much more violently to it in "Scents and Sensibility" than he did to the golden rod in a previous episode.
Zoop is a flying squirrel who has large, soft, blue eyes, and wears a short pink dress with a purple flower embroidered on her chest.
When she is describing what different smells remind her of, she mentions that she used to dye shirts in blackberry juice with her father (who, in the flashbacks, appears to be a hippie), and have frequent tea parties with her grandmother.
In his spare time, he uses the tin cans he recycles to make little statues and figurines, as seen in "Art For Iggy's Sake".
Stu is a unibrowed catfish with brown eyes, a two-part moustache, a goatee, blue-green lips, yellow scales, and sharp teeth.
He is also self-centered, cynical and egotistical; believing himself to be above everyone else in Mooseknuckle, frequently calling them all "Mooseknuckleheads", and seeing nature as nothing more than a disposable resource to implement his plans.
Robear speaks with a French accent, and wears a beret, a white shirt with red horizontal stripes, and blue jeans.
Despite all the trouble they go through for their boss, he never sees their work as satisfactory, and they repeatedly get called lazy (and other demeaning terms), are forced to sleep under a rock,[15] and their position as his henchmen is sometimes threatened.
However, he didn't want them stealing things for him from around the park, or tying up the other residents (an acknowledged talent of theirs[16]), so he devised a plan to make them work for Stu again.
They share many assumed traits of ferrets; e.g., getting depressed when separated, being afraid of deep water, and seemingly subconsciously snooping through other's belongings and taking whatever their hearts desire.
They wear white scarves around their heads, fight using swordfish like swords, and "speak" with a Japanese accent.
In "Ghost of a Chance", a few past members of the tribe are seen in the flashback as Iggy tells Jiggers the legend of two miners who upset a group of native's nighttime rituals.
The city is said to have roads paved in gold (which turns out to be golden rod), an eternally moderate temperature, and beautiful architecture.
He wears a black vest with white puffy sleeves and a number of odd ornaments such as a monocle and an aviator helmet, and rides around on a bicycle.
Iggy disbelieves in Bigtoe, but Jiggers is a staunch believer, and even carries a research kit in his backpack for any possible clues to the creature's existence.
When Iggy found out about this, he struck up a bargain with their leader Monty (voiced by Richard Binsley); in ten minutes he and Jiggers would return them to their marsh (where the hyacinths naturally grow), which they did.
Catfish Stu, however, tried to get him involved with creating a "natural" health spa, complete with electric palm trees, a giant telephone made entirely of rock, a volcano that spews out fireworks, and a geyser which erupts iced tea.
When he first came to the Kookamunga in "Pig-Coloured Glasses", he idolized Iggy for his bravery and fearless attitude, but after Jiggers saved them both from quicksand, he saw what a great uncle he had.
Because Catfish Stu was overusing the energy from the power generators, the music he played was too loud, the water in the swimming pool too hot, and the air conditioning too cold.
This dissatisfied the family, and the mother (Voiced by Ellen-Ray Hennessy; credited as Ellen Ray Snow) demanded that he give them a refund.
In "The Fish Who Came for Dinner", Stu tells Iggy and Jiggers that he would have stayed at his mother's house while the crane family hatched its eggs, but her karate group got there first.
