Mercy Watson to the Rescue by Kate Dicamillo

Mr. Watson is dreaming about driving a really fast car.

Mrs. Watson is dreaming about buttering toast, lots and lots of toast.

And Mercy Watson is dreaming about eating lots and lots of buttered toast.

Which means that when they wake up to a loud Boom! and a loud Crack! - none of them know what is going on.

Mr. Watson thinks they should call the fire department.

Mrs. Watson thinks it's an earthquake.

Mercy Watson thinks she should go check the kitchen for hot buttered toast. And if she can't find any there, maybe she'll go check with the Lincoln sisters next door...

In a series of silly coincidences, Mercy Watson, the darling of her parents' eye, rousts out the firemen, saves the day, and gets to eat a great deal of hot buttered toast. A fun set of simple stories for those just beginning to read chapter books.
