Well, I mean, everyone knows that Magikarp evolves into Gyarados. It's like common knowledge. It's also about two feet tall, so every Magikarp is bigger than your torso.
I remember back in the day this dude at a card shop asked me how much this shiny gyarados card was worth and said "perhaps $20?" and like an idiot I blurted out "try $200 easy". Could of had such a steal and bought it on the spot for $20.
He better catch it
