I seem to always forget Wooper and Quagsire are Water/Ground and immune to Electric, and when I first played through Silver I was baffled. XD
"Okay! Use Thunder Wave on the Wooper!"
Matthew glanced at Alfred unsurely. Weren't Wooper immune to Electric attacks? He bleated at his new trainer questioningly, but Alfred just looked so excited and the Wooper was being a bit of a bully…
"Mar Mareep!" Matthew sent a shock of electricity towards the Wooper to paralyze it, but the light was absorbed and Wooper was perfectly unharmed.
"What? But it's Water!" Alfred quickly flipped through his PokéDex and Dexter told him that not only was the little blue water fish Water type, it was also Ground type, thus immune to Electric attacks despite.
"Aw man! Alright then, Mattie, use Tackle!"
Matthew nodded and dashed forward to tackle the Wooper down to win the match, but the fish hopped out of his way at the last second and slapped him with its tail. "Mar…"
"Are you okay, Mattie?" Alfred called, shifting his footing nervously, unsure whether to call the fight off or not.
"Mareep!" Matthew pushed to his feet and tried to tackle the Wooper again, this time getting a direct hit, knocking it out in one.
"Ah! You did it!" Alfred cheered as the Wooper ran off and jumped back into the river. "You'll be the strongest Mareep in Johto in no time! You may even evolve soon!"
