If Merlin wants to dismantle a little metal dog and hat combo that looks suspiciously like it could maybe come from a game that might be named Monopoly in another universe, he could certainly do so and attempt to refashion the metal pieces into lock picks if he can reshape them into such.

Also, there seems to be a game with a lot of thin metal sticks. Maybe they're Pick Up Sticks, maybe they're not, but Merlin could certainly do that if he doesn't want to rip apart a tiny metal dog.
