He replaces Mrs. Puff after she is fired from her position as driving instructor, due to 's stupidity and failing too many driving tests. While teaching SpongeBob, Roderick's strict training technique of forcing him to complete the course blind-folded allows SpongeBob to drive perfectly. However, when SpongeBob begins his official driving test, Roderick does not allow SpongeBob to wear a blindfold, despite SpongeBob's training only being done with one.

SpongeBob then reverts to his old ways, rampaging across the city. Roderick, in an attempt to stop the dangerous driving of SpongeBob, sacrifices himself to stop the boat, stating that he wants Mr. Fitz to tell his wife that he loves her. His attempt is unsuccessful and he is simply flung away upon impact with the oncoming boat. It is unknown if he survived the crash or not.
