For Ayula's second mode, if either target isn't a creature or is otherwise an illegal target as the ability resolves, no creature will deal or be dealt damage.

Either of Ayula's modes can target any Bear you control, not just the Bear that entered the battlefield. Ayula can even be the target of its own ability.
