Magilla Gorilla was about a gorilla for sale in a pet store that no one wants to buy. With voice talents including Mel Blanc (Looney Tunes: Voice Artist) and Don Messick, this show was an instant classic.
When Ogee’s father refuses to buy Magilla for her, she decides to run away in retaliation. Before going to Hollywood to get a job that will pay her enough money to buy the gorilla, Ogee stops by Mr. Peebles Pet Store to tell Magilla goodbye.
After Ogee tells a friend that the Purple Mask will be coming to her house to meet her, he doesn’t believe her and asks if he can go over to meet him. However, she gets a letter from the super hero canceling his visit. At seeing how heartbroken Ogee is as a result, Magilla decides to dress up as the Purple Mask to help Ogee out of her predicament.
Mr. Peebles sends Magilla to the store to buy bananas, where he decides to ride the children's airplane ride in front of the store. However Magilla plugs the airplane ride into "high-voltage" and the little plane takes off.
A strange pet bird, a "South American Geek", comes to the pet shop. Unfortunately, Magilla is not aware that the bird has the unexplained ability to escape from any situation, and this causes Magilla to frantically try to capture the bird.
When Magilla finds out that Mr. Peebles needs a lot of money to pay his bills, he decides to become a cowboy and enter a local rodeo event to win the first prize money. Under the nickname of "Montana Magilla".
When Ogee goes to visit Magilla at Mr. Peebles pet store, the gorilla begins telling her numerous fairy tales; one of which involves a beautiful princess having to kiss a homely animal to turn him into her Prince Charming.
Magilla accidentally starts a scooter and rides it around town, with Mr. Peebles chasing after him. They then get saved by a helicopter pilot after riding over a waterfall and Magilla then decides to take another joyride, only this time in the helicopter.
