Pokemon Sun and Moon players can obtain Mega Stones for four Pokemon thanks to a code handed out by Nintendo.
The Pokemon Sun and Moon Mega Stones will evolve Audino, Beedrill, Mawile and Medicham into their Mega forms, per Serebii (thanks, Nintendo Everything).
Just enter the code INTIMIDATE and you’ll be good to go.
An end date wasn’t provided, so it’s best to hurry and enter the code.
Write that code down too, because in May, the same code can be entered to obtain Mega Stones for Pidgeot and Steelix.
