Troublemaking twins Kasey and Kelly are excited for April Fool's Day, and plan to pull a "twin switcheroo" on their classmates to see if anyone notices the difference.

April Fools' Day is long and hard for the third-grade Huit octuplets, but it is nothing compared to the challenges of Tax Day, through which Jackie discovers her special power and gift and learns more about their parents' mysterious disappearance.

At Green Lawn Elementary, the entire school becomes involved in a mystery when Mr. Bones, the skeleton in the nurse's office, disappears.

It is April Fool's Day, but Max needs to learn that not all pranks are funny.

April Fools' Day is not a happy one for Wagner the mouse because his best friend, Pearl the rabbit, and other children and adults at school keep tricking him.

"The My Weird School kids are fed up with Miss Banks and her constant pranks. They decide to finally prank her back. After seeing how focused and engaged the kids are with their practical joke, Mrs. Stoker suggests a week-long prank competition between the students and the teachers. If the kids manage to pull off a win, theyll get a candy party. And so begins the most epic prank war that Ella Mentry School has ever seen!"--
