OOC
Leaving the wolves for later means having them struggle against their chains the whole time we're loading, while the party is either split and/or encumbered in the event that they break free. We just killed 2 wolves and a small army of goblinoids at the same time, three wolves that we can free individually should not pose a threat we're afraid of at this point. I mean, they're not evil monsters out to kill us, they're starving animals chained up in a room.
We can feed them some goblins first, then free them once they've got their bellies full, that should further reduce the chance of being attacked. If we leave them the whole time though, we're giving them a reason to try to break free every time we walk passed them. If they have a clear escape when we set them free, they're probably going to take it. If they break free while we're taking stuff, and the exit isn't clear, or they break out in between two of us taking loads, then someone's probably getting attacked because there is no easy exit for them and they're feeling trapped.
