A kid goes somewhere in pajamas (by mistake)

A family dog that will eat everything, but burps after every meal, and is just like the third-grade owner of the dog.

Try putting animals in funny situations. Its pretty easy. Just pick an animal that’s funny (like a goat). Then make the goat do something weird (like drive a car). Then just put the two together into a title: The Day my Goat Drove Grandpa’s Car.

You can also write a more serious book. If you do that, still make it somewhat lighthearted. What comes to mind is this book about a girl who decorates the subway station in her town with drawings. You can write the same sort of book by taking an ugly place, or something that needs to change, and having an elementary student change it. voila! A great idea for a book!

Good luck!
