A potbellied pig and an iguana ditch their petting zoo home for freedom in this webcomic-turned–graphic novel.The escape plan starts with chaos: A miniature train crashes through the zoo's gate. Next, Pigmund Isidore Pigmund (a pig) and Lizárdo Van Buren Van Halen (an iguana, allegedly) ride off on getaway chickens as the zoo's maintenance man chases after them. In the outside world, a pampered Chihuahua inspires the runaways to seek out "SWEET PET PERKS." The duo then declare themselves "FREELANCE PETS," meaning they "can walk away from their dumb pet job ANY TIME THEY WANT." After creating business cards on the backs of pizza boxes, they go door to door on a "Finding Business Quest." Eventually they find their ideal customer-on their 74th try. That is, until a hamster warns that things might not be what they seem. This pseudo-autobiographical comic (told from fictional pig to real-life human Messner) is divided into five "adventures." Messner's black-and-white illustrations, often borderless, give a DIY comics feel. The style fits well with Pigmund's over-the-top, self-referential first-person narration. Circuitous storytelling situates Pigmund as a delightfully unreliable narrator who even occasionally teases withheld details. All human characters' skin is the white of the paper.Hog wild hilarity. (Graphic fiction. 9-12)
