S1E6 The Gum Leaf War

Following a mishap, Linda finds herself nursing a broken nose. In her dreams, it appears oversized, prompting her to retreat to the countryside with her Aunt Tuneless, who bears a striking resemblance to Nell. There, she uncovers a peculiar secret: playing "The Wild Colonial Boy" on a specific gumleaf allows one to transfer illnesses to others. This revelation hits her when Aunt Tuneless employs the technique against Foxy, a character reminiscent of Mr. Gribble, who has a son resembling Gribble Junior.
