The continuing story of Hank the Pet Sitter and his friends began in Set 1 with the first day of summer, and Hank’s bike was ruined by his own dad! How could his dad not see the glint of bike fender in the moonlit driveway? Hank's parents want him to be responsible, so Hank needs to raise money for his next bike. Hank starts a pet sitting service, which often costs him almost as much as he takes in!
