To change Buffy's staking arm position, I boiled a pot of water, turned off the heat, and held Buffy's body under the water for about a minute. When the vinyl softened, I just bent Buffy's arm in the position I wanted using a towel (the plastic is hot). I held the arm in that position until the plastic cooled, about a minute or two. Voila! Slay-ready Buffy!
