Why did the wolves alert the goblins to the adventerers who are hiding in the trees?

The wolves alerted the goblins to the adventurers hiding in the trees due to their keen sense of smell and heightened instincts. As natural predators, the wolves detected the unfamiliar scent of the adventurers, perceiving them as a potential threat to their territory. Additionally, the wolves may have been motivated by a territorial instinct or a pact with the goblins, leading them to inform the goblins of the intruders' presence. This collaboration highlights the interconnectedness of creatures in their environment.
