when i was 6 and my brother was 11, i just started playing ruby. he had been playing sapphire for a few years, and he almost completed his perfect team, while i was trying to figure out how to throw a pokeball. Anyway, i used rock smash on one of the rocks outside of mauville city and ran into a geodude. this was my fourth pokemon (my team was marshtomp, silcoon, and ralts), two gyms later, it was a graveler, and it was the powerhouse of my team. At the time, i was really naive about pokemon and my brother convinced me to trade him the graveler, because he said "it will make it learn a secret move". Of course, it evolved into a golem, and i got an egg that hatched into a tentacool.
