When Henry and his dog Mudge go with Henry's parents to visit Great-Grandpa Bill in the home with lots of other grandpas, they lead them all on a wonderful adventure.
At first Henry's very neat cousin doesn't like the cookies from under his bed or Mudge's slobbery kisses, but when they all play frisbee, she begins to enjoy her visit.
Annie takes her rabbit to the home of her new friend, Sarah, to play and enjoys seeing the pretty house full of frilly things, walking in the beautiful garden, and making a tiny garden house for a fairy tea party.
