Mighty Mega Pets: Walker Books

After eating weird, tainted pet food, Daisy the dog, Bubbles the fish, and Ginger the cat suddenly get superpowers! (Although Arthur the tortoise is still non-super. And grumpy.) Together they're the Mighty Mega Pets, and they're determined to get to the bottom of the pet food mystery. But they must face down a rival super-pet gang called the Ruffians and their leader Guinea Big, the villainous guinea pig. With a giant bunny with spaghetti arms on a rampage and the bad guys' nefarious plan to cover the whole town in vile Super Substance, the team must rely on one another, surprising new friends, and maybe even a grumpy tortoise to save the day. A hilarious page-turner.
