Lilly was originally a wish rabbit. After her partner died shortly after the purchase, the owner decided to save a second rabbit. So Lilly got Balu as her new partner. Then, when a few months later the owners found out that they were expecting their own offspring, happiness seemed perfect. It was only after the baby was born that the problems began. The child was not well, and then the horror diagnosis: the child was allergic to rabbit hair. The animal lover asked for her two charges to be taken in, and so now Lilly and Balu have become Aiderbichlers.
