Wilbur's pretty cousin comes to visit and he sets up a plot to have her make a play for Natch. However, she ends up making a play for Jackson instead.; When Katie and Portia have to let Natch and Jackson use the Kilroy's record player, the girls decide the town needs a clubroom just for girls. To raise funds for the project, Katie organizes a benefit dance for the girls' parents (featuring Lawrence Welk), and has everything set--except that she forgot to budget money to pay the band.; Depressed because all the girls have gone to summer camps for a month, Natch and Jackson decide to go camping on their own. They accidentally pick a spot on the lake that's right by Judy's and Portia's camp.; Mr. Kilroy forgets to mail the bonds on a half-million dollar deal. He calls Natch to have him take the bonds to the airport and send them registered mail. On the way Natch picks up Jackson on his way to a music lesson. As expected, Jackson takes the bonds to his music lesson and Natch sends Jackson's sheet music to California. It all turns out all right in the end, though there are side trips to the city dump and California.; A boy passes up a chance to attend a big dance in order to "baby-sit" the Fosters' teen-age niece.
