I accidentally encountered a Corphish in the western pond of Suntouched City. It used a move called Dark Sonata, and intruiged by it, I caught the said Corphish. When I tried using the move against an opponent Audino in my Secret Base, it used the move, and Corphish transformed into the opponents Audino, copying all the moveset it had. As I tried switching out to a different Pokemon, the game screen froze but the game was still on (the D-pad was still functioning but the A B buttons weren't).
