While Grim waited patiently, he spotted what, at first glance, appeared to be a werewolf, and it was padding towards the entryway to the maze. Grim looked closer and discovered that it was a unicorn in diguise, and a very good disguise at that. He debated with himself to tell the pony that the maze was innaccessable until one of the Princesses started the Challenge, but decided to tell them after they tried to get in. So, a smile creeping onto his face, he just sat there and watched for other ponies to approach, waiting for the unicorn to come back from failing to enter the maze.
