PaRappa, having won a lifetime's worth supply of
instant noodle products from Beard Burger's burger shop, has become nothing short of weary from eating nothing but noodles for every meal every single day. When PaRappa complains about being served noodles by his crush, Sunny Funny, he becomes shocked when she calls him a baby, causing him to question his own
maturity. PaRappa and his friend P.J. Berri decide to eat at Beard Burger instead, where they shockingly discover that for some reason, the burgers have turned into noodles. From a poster, the Beard Burger Master, the founder of Beard Burgers, comes back as a ghost and helps PaRappa make a "Traditional Parappa Town Burger". Afterwards, PaRappa and P.J. learn that a mysterious phenomenon is turning all the food in town, not just burgers, into noodles. Papa PaRappa and General Potter, PaRappa and Sunny's respective fathers, try to develop an invention that can stop the "noodlization." However, they inadvertently shrink themselves in the process. PaRappa and P.J. then participate in a workout on an adult show run by Chop Chop Master Onion, not knowing that their fathers are stuck small by Papa PaRappa's invention. PaRappa presses a remote for a different T.V. show but accidentally shrinks both P.J. and himself, along with their friends and some other people. They are soon helped out by the Guru Ant and return to normal size. After undergoing army training under Instructor Moosesha, PaRappa helps rescue Hairdresser Octopus from being hypnotized into giving people afros. Later, PaRappa discovers "Food Court", a
video game cartridge, to be the cause of the "noodlization". PaRappa's father warns them that if a player loses the game, the cartridge will curse them to only be able to eat noodles. Despite this, PaRappa insists that he should be the one to complete the game. Upon winning the game, PaRappa's father reverse engineers the cartridge to create a device that can reverse the noodlization. PaRappa and the others use sweets and the de-noodlization devices to combat against the Noodle Syndicate, who are behind the town's noodlization. They soon confront the mastermind, Colonel Noodle, who is revealed to be the son of Beard Burger Master. Similar to PaRappa's situation, he grew wary from eating burgers for every meal all his life (not helped by it causing his friends to rejecting him on his first birthday party, and his mother turning into a burger from eating so many), deciding upon discovering his love for noodles that they should rule the world instead. Thankfully, PaRappa manages to convince him to be more open-minded about various types of food, and he becomes good. As everyone celebrates in a party from MC King Kong Mushi, Sunny assures PaRappa that he's more mature than what he thinks himself to be. Everything returns to normal, excluding the situation repeating itself when he wins a lifetime supply of
cheese. ==Soundtrack==
