Expedition into the cave.

The hobbit’s arrow whistled through the darkness and hit the humanoid right on target, who let out a nasty croak. If June had paid attention to the wound (and no one else could, as their vision was blurred), he would have realized that it was quite serious. But June was too busy watching as the humanoid rapidly increased in size and grew fur, its hands turning into wings, and its ears sliding back on its head and becoming triangular. A ringing sound was heard: the arrow fell out of its wound and landed with its metal tip on the stone. However, the wound was already gone; whatever this creature was, it was completely healed.
