Skinner, enraged by the food's delicacy, chases Remy throughout the Gusteau's restaurant, trashing it in the process. Remy decides to cook Ratatouille for the night, impressing Ego.

Now it is up to Remy, his rat colony, Linguini, and Colette to cook for many people, including the critic Ego. However, with the exception of Linguini and the rôtisseuse Colette, they all leave after finding out about Remy. After that, the food critic Anton Ego, also known as the «Grim Eater,» has arrived at Gusteau's for a review one that will be important to the cooks. Later, Remy helps his colony steal prized foods at the market. Skinner catches Remy, and another chase is on, ending up with Remy discovering a letter that proves Linguini's right to inherit the restaurant, leading to Skinner's firing. The next day Remy helps Linguini cook the food for the customers while also helping his colony that he has reunited with by stealing the kitchen's food. After that, Remy joins Linguini and helps him with what he is forced to do for Skinner, the head chef. Remy drops in and fixes the soup, but Linguini witnesses him, thus beginning a chase outside with Linguini on pursuit. After Remy successfully escapes the shotgun-wielding woman, he is caught in the rapids of the sewers, and he wakes up in front of Gusteau's restaurant, where the rat witnesses the garbage boy, Linguini, attempting to fix the soup he accidentally ruined by scrambling in a bunch of random ingredients. After the task, the old lady living in the farm catches Remy and Emile, alerting the colony, thus forcing them to escape. On the trek he is taught the basic skills he will need to know so that he can accomplish what he faces later on. Remy goes off with his brother Emile to retrieve apple cores for his father. Similar to the plot of the movie, the game starts in a farm setting. Another large part are mini-games, many of which involve cooking, with Remy having to pick ingredients or peel potatoes.Several of the actors from the film voice their characters in the game. Other sequences in the levels involve sliding down pipes, rafting through water currents and fleeing from humans that chase Remy. Sometimes, Remy must evade guards by hiding out of sight until their attention wanes. He can also engage his keen sense of smell, which displays the path to the next goal or objective. To get around in the various levels that include the sewers, streets and rooftops of Paris, the restaurant kitchen and a food market, Remy can jump and double-jump, swing along poles, balance on ropes, crawl on certain walls and defend himself with tail swipes or by using spoons as weapons.

While many of the environments in the game are similar to those in the next-generation version, this version has almost none of the open world elements seen in the other title, with smaller levels and mostly linear progress. When Remy finds himself in Paris near the restaurant of the famous deceased chef Gusteau, he works on making his dream of becoming a chef himself come true, while helping out his fellow rats to procure food. The player controls Remy, a rat with a refined sense of taste. The game follows the plot of the film only loosely, but has the main voice cast from the movie reprising their roles. The version by Asobo Studio is, like other versions, a 3D platform game, but has its own design, levels and missions. Description Ratatouille is based on the Pixar film of the same name.
