The show was hosted by Jake the Polar Bear and Stinky the Skunk who interview 2 of each and every animal of the Animal Kingdom per show (there are some episodes where they only interview one animal because of its many types).
Jake the Polar Bear (performed by Steve Whitmire) - The host of the show. He always asks the clever questions. With Jake being a Live-Hand Muppet, Steve Whitmire is assisted in performing him by Bill Barretta who operates Jake's right hand.
Stinky the Skunk (performed by Dave Goelz) - The co-host of the show. He always asks the ridiculous questions.
Ollie the Tapir (performed by Karen Prell) - An enthusiastic, nasal-voiced tapir who was paired up with Armstrong in Season One. She would also be the one who would bring in any animal guest that required assistance (mostly the insect ones). Ollie the Tapir was dropped at the end of Season One.
Bunnie the Bear (performed by Louise Gold) - Jake the Polar Bear's cousin. She joins the show in Season Two after Ollie the Tapir was dropped during the production of this show. Like Ollie the Tapir, Bunnie the Bear would bring in any animal guest that required assistance (mostly the insect ones).
Tizzy the Bee (performed by Karen Prell in Season One, Louise Gold in Season Two) - A bee would pop in to ask Stinky and Jake some animal-related questions. Tizzy was later dropped from the show before Season Three. She is a computer-animated Muppet similar to Waldo C. Graphic.
Rhonda Rat (performed by Louise Gold) - A rodent reporter who joined the show in Season Three. She often asks any animals backstage animal-related questions. When Rhonda gets annoyed by the animal, she has the animal sent down the trap door.
