Saving matches
When controlling Peter, light a fire and walk up to it. He will have a big branch in his hand to use for protection, but as you stand near the fire the branch will catch on fire. If there is another stack of sticks nearby that you can light, you can use Peter's branch to light the fire without having to use any matches. You must do this quickly because the fire on the branch dies down after about six or seven seconds. Note: This will not work if Peter is wearing his suit of armor.
