I used those Command Hook things that they said we could use to hang stuff up in the dorms because they don't go into the walls and aren't supposed to mess up the paint. Please - the only people they'd need to worry about waging skeleton war is me and Sans. And we'd hardly do that in the hall. Not enough space for a decent battlefield.
We can. Maybe carve some after we paint them? See what the candles do to the paintjobs?
