In a suburban San Fernando Valley garden in Los Angeles,[12] Theo, self-named "Turbo", is a garden snail who dreams of being the greatest racer in the world, just like his hero, five-time Indy 500 champion Guy Gagné. His obsession with speed often makes him an outcast in the slow and cautious snail community, and a constant embarrassment to his older brother, Chet. One night, Theo wanders onto a freeway to admire the traffic and wishes upon a star, later revealed to be an airplane, that he was fast. Suddenly, he is sucked into the supercharger of a Chevrolet Camaro drag racer, fusing his DNA with nitrous oxide. When he wakes up, he possesses great speed and accuracy, and some characteristics of a real car. However, his first attempt to try out his new powers ends with him crashing a tricycle into the tomato garden in which they and many other snails work, resulting in him and Chet to get fired from the garden crew.
