Pig Pig is reluctant to leave his mother and Fluffy the cat to spend his summer vacation road tripping with his Aunt Wilma and Uncle Fred. Pig Pig would rather stay home and build a rocket ship model or read back issues of Daring Pig Exploits. Besides, his mother and Fluffy might miss him too much. His uncle insists that this is the opportunity of a lifetime, and soon Pig Pig is enjoying an eye-opening road trip. But he worries—what if his mother and Fluffy don't remember him when he gets back?
