Picture-Picture reads "Hi" as Rogers enters with a scuba-diving doll, underwater mask and snorkel. He wears the mask and snorkel temporarily and runs the doll in his bathtub. As he fills the bathtub with water, Rogers puts in several toys, including a rocking chair. Then he operates the scuba-diving doll. He imagines that it is exploring the ocean (film insert). Mr. McFeely calls to say he has found his delivery for Rogers.
Still nighttime in the NOM, Chuck Aber, dressed in full scuba gear, "swims" by, frightening Henrietta. He tells her he plans to go scuba diving at the Southwood lake with Betty Okonak Templeton. When Aber "swims" to the Factory, Corny has his underwater rocking chair, a present for Templeton, ready. As Aber goes past the Museum-Go-Round, Lady Elaine mistakes him as a visitor from another star. Aber alerts her to Corny's underwater rocking chair. Lady Elaine agrees to call Corny before she goes to the Factory. Aber asks that the Trolley (on the auxiliary tracks) take him to Southwood, where Carrie Dell is crying. James Michael Jones and a scuba-masked Betty Okonak Templeton don't know what is making Carrie Dell cry. Aber takes off the mask, and when Betty shows her true face, Carrie Dell settles down, uttering her only on-air word: "Mommy."
Back at the television house, Mr. McFeely brings Rogers a full firefighter's uniform: boots, pants, jacket, helmet, and mask. Rogers puts on all the items. After McFeely's visit, Rogers plays quiet music. He gives viewers a word, "soporific," which means "making one sleepy."
