They look so cute but this friendly behaviour ultimately ends in a fight for the beanbag. It starts with Willow (Grey) sitting on the beanbag. Oscar then comes along and decides he wants to sit with her, so makes himself comfortable. This leads to a prolonged cleaning session with Willow and Oscar fighting to be the first to clean each other. After a while they stop cleaning each other and start biting each other until one of them gives up (usually Oscar) and leaves the beanbag.
