First, I'll introduce a series called Mercy Watson.
The author is Kate DiCamillo.
The first book is called Mercy Watson to the Rescue.

Here's the summary:
To Mr. and Mrs. Watson, Mercy is not just a pig — she's a porcine wonder. And to the portly and good-natured Mercy, the Watsons are an excellent source of buttered toast, not to mention that buttery-toasty feeling she gets when she snuggles into bed with them. This is not, however, so good for the Watsons' bed. BOOM! CRACK! As the bed and its occupants slowly sink through the floor, Mercy escapes in a flash — "to alert the fire department," her owners assure themselves. But could Mercy possibly have another emergency in mind — like a sudden craving for their neighbors' sugar cookies? Welcome to the wry and endearing world of Mercy Watson — an ebullient new character for early chapter-book readers in a series that's destined to be a classic.
Suited for children(age):6-8

The second book: Mercy Watson Goes for a Ride

The summary:
Mr. and Mrs. Watson's porcine wonder, Mercy, loves nothing more than a ride in the car. It takes a fair amount of nudging and bribing and a "You are such a good sport, darling" to get the portly pig out of the driver's seat, but once the convertible is on the road, Mercy loves the feel of the wind tickling her ears and the sun on her snout. One day the Watsons' motoring ritual takes an unexpected turn, however, when their elderly neighbor Baby Lincoln pops up in the backseat in hopes of some "folly and adventure" — and in the chaos that ensues, an exuberant Mercy ends up behind the wheel! Soon there's a policeman on her tail, a struggle for the brake, and a blissfully airborne Mercy. Of course, it's nothing that an extra helping of buttered toast can't fix!
