A beast
The loggers were shocked by what they had found in the tree trunk. At first glance, what had been trapped in the tree looked like a monster leaping straight at you. It also was somewhat reminiscent of a wild dog, baring its teeth and growling at you. Everyone seemed to have seen a different kind of creature, but they agreed on one thing: it was a living being.
Or rather, the creature had once lived. It had been in the trunk for a while and had been dead for quite some time. The loggers became more and more curious about what it was exactly. They couldn’t wait to learn more about this monster or beast. And of course they were also very curious about how it had ended up in the hollow tree.
