if i catch 2 spindas will they have different spot patterns in game or will they look the EXACT same(not shiny)
Spinda's spots are based on a hidden mechanic called personality value. There are 4294967295 different personality values so the chance of catching two of the same spinda's are very rare.
They will be different somehow. No two Spindas have the same spot pattern (according to what the game says...).
