When all the tires on the Adventure Bay schoolbus blow out, Rocky has to help repair them. Meanwhile, the kids still need to get to school, so Ryder volunteers to use the Paw Patroller as a substitute schoolbus. The kids have a great time on their new bus, but then are accidentally launched out on the pups’ vehicles! Now the pups must go all over town to rescue the kids, their rides, and get everyone to school on time!
