Percy the Pug and Petunia the pig are the very best of pals . . . until Petunia wins a blue ribbon at the county fair. Suddenly, she has no time for hide-and-seek or lapping puddles, cheek-to-cheek. But when Percy finds a faded comic book in a puddle, the lonely pug dons a cape and takes on a new persona: THUNDER PUG! Even though being a superhero is exciting, Percy knows he's missing something. Only when "Pink Lightning" (aka Petunia) joins him, and the two are "side by sidekick" again, are they truly living the heroic life!
