Episode Information

"Tough Cookies" is the thirty-eighth episode of the fourth season, and the one-hundred-eighty-seventh episode of The Loud House.


Lincoln and Clyde start their own cookie-making business, but find that it's a lot more work than they realized.


At the elementary school, Clyde approaches Lincoln with a plate of cookies. After Lincoln takes a bite of one, he expresses how much they taste good. At that moment, Principal Huggins, complaining about the excessive use of floor wax, arrives and Clyde offers him a cookie to make him feel better. After he takes a bite, he loves the taste and asks if the boys could make some more for the school board meeting tonight, because Superintendent Chen has a sweet tooth, and they agree when he says he'll pay them.

The King of Cookies

Later that day, as Principal Huggins and Superintendent Chen walk down the hallway, Lincoln and Clyde arrive with their plate of cookies. Huggins offers Chen a cookie, and once she take a bite, she loves the taste so much, she asks the boys if they have their own cookie making business. After daydreaming of running a business called "CM Cookies", Lincoln and Clyde realize that they could become "the Cookie Kings of Royal Woods" and agree with Chen's decision and decide to start their business, while also shafting their history project.

The next day, Lincoln and Clyde go around town to gather orders. They receive orders from a man whose anniversary is coming up, Lynn and her soccer team, Lynn Sr., and the elders of Sunset Canyon. At the McBride house, Lincoln and Clyde get to work on their first dozen, which includes making the cookies, wrapping them and Lincoln providing a comic for each individual wrapper. Once they finish their first dozen, they realize, to their horror, that it took them four whole hours to make them. As the boys look over their list of orders, they suddenly get a call from Lisa (who was listening in from the boys' walkie-talkies), who tells them that all their orders will take them two days to complete. She suggests that they hire some other workers and find a bigger place to bake (where she's revealed to have countless security cams all over Clyde's house).

At the Loud House, Lincoln and Clyde get Zach, Stella, Rusty and Liam to help them out. However, their incompetence makes their progress a lot slower, as Clyde does Stella's work when she's too aggressive, Zach ends up taking a bite of the complete cookies, Liam bringing a cow to produce more butter, and the cow destroying their conveyor belt to mass-produce the cookies faster. This prompts the friends to leave, saying that they got to work on their history projects. This announcement makes Lincoln and Clyde realize to their horror that they forgot to do theirs, so they promptly get to work on making the cookies in such a rapid pace, and despite some injuries, they manage to complete every order.

Lincoln and Clyde proceed to go around town and drop off their orders. When they drop their order off to Lynn Sr., he congratulates them for at least trying to start a business, reminding them that starting one can be too much for two young people. At the school, Lincoln and Clyde apologize to their friends for the hassle they put them through and reveal that they used some of their leftover cookies for their own project: a replica of Stonehenge (even though they have bite marks from Zach).


Pop-Pop, Seymour and Bernie have no lines in this episode, but they can be seen picketing outside of the retirement home with the other seniors.
