What onomatopoeia in in the watsons go to Birmingham?

Oh, dude, in "The Watsons Go to Birmingham," there are a few onomatopoeias like "Boom!" and "Bam!" that are used to describe sounds in the story. It's like when you hear a loud noise and the author is like, "Let's make it sound exactly like it is." So, yeah, those are the onomatopoeias you can find in the book.
