Summary: Darrin's mother insists on paying Tabitha's tuition at a nursery school. Worried about Tabitha's witchcraft, Samantha plans to spend the first day with her. Mrs. Burch, director of the school, won't let Samantha stay and Mrs. Stephens takes her shopping. Before leaving, Samantha warns Tabitha against witchcraft. At a dress shop, Samantha goes into a dressing room and pops out to check on Tabitha. The saleslady is surprised to find the room empty and even more surprised when Samantha pops back. Playing a nature game, Mrs. Burch tells Little Amy Taylor to be a toad. Amy sobs she wants to be a butterfly and Tabitha grants her wish. Amy flies out of the window.
Samantha finds Mrs. Burch upset by Amy's disappearance. When she learns what happened, Samantha chases the butterfly into a tree and then onto the 19th floor of a building under construction. Startling the workmen by appearing with a butterfly net, Samantha takes the butterfly back to school and Tabitha changes her back. Hearing Amy's story, Mrs. Taylor thinks its just vivid imagination. Mrs. Stephens wonders why she didn't see Samantha leave the shop. Reporting on Tabitha's first day, Samantha tells Darrin that Mrs. Burch has closed the school to avoid a nervous breakdown.
