“Stones! Stones! Get yer stones right here!”
It’s Friday afternoon and that means my brain is dead for the week, so I’m imagining a stadium vendor / concessions-seller / hot-dog man in the Pokémon universe, selling his Mega Stone wares.
With the code MATSUBUSA, you’ll get the stones needed to Mega Evolve Sceptile, Blaziken, Swampert, Camerupt, and Banette in Pokémon Sun and Moon. Just head into the Mystery Gift option from the main menu, select Receive Gift, enter the code, and pick up your package at a Pokémon Center.
