Season 1

When Judy trades Slick her broken wristwatch for an item that will allow Alan to escape from the game, the three of them get back home to Brantford only to discover that time has stopped, the annoying chimps from Jumanji have come back with them, and Peter is slowly being transformed into a turtle as punishment for Judy's attempt to cheat Slick.

After an encounter with the school bully and his gang, Peter decides to stay in Jumanji and is slowly transformed into a Manji mask-warrior, while Alan discovers the key to the secret back door of Jumanji.

When Aunt Nora is sucked into the game, the kids and Alan must rescue her from the clutches of Van Pelt.

When Peter brings a computer with him into the game to help figure out how to rescue Alan, it falls into the hands of a mad inventor who uses it to gain control over the inner workings of Jumanji.

When Alan steals the dice so that the kids will no longer be put in danger by visiting Jumanji, Peter figures out another way to get into the game and they discover the mechanical underworks of Jumanji where they are chased by The Stalker, and Jumanji transforms Peter into a toucan.

After Judy is ignored by a cute guy at school, who only pays attention to her when he wants her to do his homework, Jumanji conjures up a dashing adventurer who resembles him, to sweep her off her feet, but he transforms Peter into a stone statue.

Alan manages to turn Van Pelt's own tactics against him and defeat the hunter, but Jumanji simply replaces him by transforming Peter into a miniature replica of Van Pelt.

Judy and Peter are trapped in a time loop which ends with Peter getting killed, and they keeping reliving it until they figure out how to save him.

When Peter takes the game to school to impress a girl he likes, both she and the school bully are transported to Jumanji along with him, but the game makes it appear that the bully is daring and brave, whereas it transforms Peter into a wild boar.

The queen of a Jumanji tribe of amazons is after Alan, but complications ensue when Aunt Nora is sucked into the game again and challenges the queen for his favors.

When Alan is poisoned by the bite of a Jumanji centipede, the kids must find an antidote while evading the combined onslaught of Van Pelt, Trader Slick, and Professor Ibsen. And Peter lies again and is transformed into a frog.

When the kids and Alan finally escape from Jumanji, Peter brings a harmless-looking animal back with him which proceeds to grow bigger (and hungrier) every time he tells a lie and soon threatens all of Brantford.
