Even though Candy Moore, Jimmy Garrett, and Ralph Hart were still contracted to the series, they were used minimally during the third year. For example, in the episode "Lucy and The Old Mansion", which was the final Season 3 installment, filmed in January 1965, Moore, Garrett, and Hart appear in the opening scene, have a few lines of dialogue, then exit. It is the last time in which all of the three children are seen, and they were subsequently written out in Season 4. Dropping Candy Moore, in fact, was Ball's decision. Because Moore was very popular with teenagers and the subject of dozens of articles in youth-oriented magazines at the time, her departure was originally nixed by CBS but finally accepted when Ball threatened to "retire."
