S1, E22: When Ned starts to feel that everyone gets visitors but him, he decides to invent an imaginary friend, “Big Benny”, who comes to stay with him in the caravan. Ned has fun taking Big Benny on a picnic, buying extra ice-creams for him, and playing games. Frank and Buster decide to invite Ned and Big Benny to tea, to make sure that Ned is okay. Ned reveals that Big Benny doesn’t actually exist, and that he just wanted to have a visitor like the Koala Brothers. Frank and Buster let everyone know that Ned would like a visit, and the next day, Ned has a line of guests who’ve all come to see him. Even Penny arrives to say hello! Ned is thrilled, and Frank gently suggests that to have visitors, you just need to invite them! Ned is sure to have all the visitors he wants in the future.
