[X] Bite the creature free.
Someone is coming. Someone with the ability to create and use fire, which either means that it's a magical creature, or it is intelligent. Both are things that you don't want to meet, not now.
But what about the creature...
You think about it for a moment, then you decide to set it free. Your teeth make short work of the thing attaching the creature to the tree, then you float up, above the reach of the creature in case it becomes hostile. It merely looks at you in confusion for a few moments, then focuses on untangling its foot, though.
You float up and towards the source of the light, trying to discover what is approaching the both you. You see a bigger version of the creature, only its skin is a lighter colour, and its ears are rounded, rather than pointed. Its body is covered with dead organic material too, and a large piece of dead skin on its back is filled with stuff. It is carrying in its hands a piece of wood with a sharp metal shard attached to the top, and a burning piece of wood, which was the light you saw.
Hm...
[] Float back and tell the creature about larger-version-creature.
[] Stay in the sky and watch what happens.
[] Float down and follow it silently, taking offensive action if it does too.
[] Write in.
