This is Herself's very first koala, from eons and eons ago. (I think there were perhaps five koalas in all, though I cannot quite recall. There are several in the house here.) She carried her koalas with her frequently. In the family tradition, she even had what was deemed the "tooth koala" instead of the "tooth fairy". There were eventually koalas both big and small. She kept her love of koalas for many years, until she moved on to more teenage-girl-specific creatures like unicorns.
This is the one that started her particular enjoyment of koalas. Its fur is quite flattened and its little claws are worn off nearly completely, but its eyes and nose are still firmly attached. It's a good koala, indeed.
