Meanwhile, Louise, Gene, and Tina try to help their parents by coming up with ways to increase their revenue.

As they prepare for the musical, a group of rats enters the restaurant, causing chaos and disrupting the Belchers' plans. Bob tries to chase them away, but the rats are too clever for him. They are eventually able to trap the rats and remove them from the restaurant.

However, Bob and his family face another obstacle when they discover the identity of the new restaurant's owner: Felix Fischoeder, the brother of the Belchers' unscrupulous landlord, Calvin Fischoeder. Fischoeder seems to be trying to drive Bob's Burgers out of business so that he can expand his own restaurant. The Belchers attempt to strike back by staging a protest outside of Fischoeder's restaurant, but it doesn’t go well.

The family comes up with a new plan to save their restaurant from Fischoeder's attempts to put them out of business. They mount an elaborate horse costume on the wharf and position it so that it covers the other restaurant's sign. The plan works, and customers start coming back to Bob's Burgers instead of going to Fischoeder's restaurant.
