Here are some ideas I thought of for future episodes of The Loud House
Lincoln accidentally gets locked in Lisa's bunker.
Leni tries to babysit Lily.
Lincoln's class is having an art contest, so he asks his sisters for ideas.
Lola reads out Lincoln's diary to the whole family, humiliating him in front of everybody (Similar to the Spongebob Squarepants episode "Little Yellow Book")
Lincoln accidentally breaks Lori's phone, but Lori accidentally injures him.
When Lily drinks one of Lisa's experiments, she gets the ability to talk.
When Lincoln watches a zombie movie, he has a nightmare that his family turns into zombies.
Tired of his sisters fighting, Lincoln sets up some rules.
Feel free to put your title suggestions in the comments
