Mister Rogers arrives with a friend's automatic camera which he uses to take a picture of his fish tank. While he waits on the photograph to develop, he sits at the kitchen table and draws a picture of his fish. Cutting out the paper fish, Mister Rogers attaches it to a stick that he can carry with him. Moving to the couch, Mister Rogers shows pictures of animals dressed up for a pet show before singing Everybody's Fancy. In the Neighborhood of Make-Believe, Ana Platypus wants a pet for her birthday and King Friday brings out his own pet, Troglodytes Aedon, and sings to the bird on a stick. Meanwhile at the Museum Go-Round, Lady Elaine opens the Concourse of Catalogues where she displays pictures of different kinds of pets for Ana to choose from. Back at the house, Mister Rogers sings a song of his own to his fish on a stick, Sally Margaret McFarland. He then spends some time thinking about different ways children play with their pets. After talking about a time when someone allowed their pet to jump up on him, Mister Rogers sings I'm Angry. Bob Trow stops by with his dog, Barney, so Mister Rogers can get to know him before dog-sitting for a night. After they leave, Mister Rogers sits on the swing and talks about responsibility before calling Mrs. Rogers to see if it's okay to dog-sit. Part of the "Mister Rogers' Neighborhood" series.
