Let's celebrate grandparents! Meet the older generations of some favorite PBS KIDS families through fun, grandparent-focused stories. Arthur gets knitting lessons from Grandma Thora; Rosie celebrates her Abuela's birthday from far away; Daniel is excited to spend the whole day with Grandpere; Donkey Hodie and Grampy enjoy some homemade chili together; and much, much more.

It's a wonderful day for Spot. He is spending the day with Grandma and Grandpa and they are taking him to the carnival! And there's an extra special surprise in store. Spot and his friends get to ride in the carnival parade on an actual fire engine! But when the float with the carnival's band gets a flat tire, who will save the day?
