This mother koala is not afraid to voice her dissatisfaction, and lets her neighbor know that she is not happy with being denied her desired perch. Often incorrectly referred to as koala bears, koalas are actually a marsupial. Joeys spend their first six months inside their mothers pouches, and another six or so travelling on their back like this one, providing them with a front row seat to all social activities including altercations!
