Let's Celebrate Pets There is no friendship quite like a friendship with a pet. Pets give every pony companionship, joy and can even make the world a better place. You can depend on pets to help you out in ways that pony friends might not be able to. There's no doubt that ponies love pets just like they love parties. However unlike pets, parties can be very stressful affairs! Contains episodes 6 to 10 of Season 2.
