The Pokemon GO community is usually quick to figure out tricks to control the evolution of certain Pokemon. Mere days after the game launched in the summer of 2016, and the Eevee evolution trick was discovered. Not long after Tyrogue was added to the game, and many trainers realized that the Pokemon’s stats are what determined whether it would evolve into Hitmonchan or Hitmonlee. However, the evolution of Wurmple has fans stumped, and it appears as though it’s completely random.
In Pokemon GO and other Pokemon games, Wurmple evolves into either Cascoon or Silcoon. Cascoon then evolves into Dustox, and Silcoon evolves into Beautifly. Pokemon GO players that don’t want to catch a ton of Wurmple will want to control its evolution so they can obtain all the Pokemon in its evolutionary line, but so far none of the theories on how to do this have been proven.
Since Eeevee’s evolution can be controlled by giving it a certain nickname, some fans assumed that controlling Wurmple’s evolution would be similar. However, naming Wurmple after characters from the anime doesn’t seem to have any effect on whether the Pokemon evolves into a Cascoon or a Silcoon. Other players looked into the possibility that Wurmple’s stats would determine which Pokemon it would evolve into, similarly to how Tyrogue’s evolution works, but no data supports this theory either.
One theory that seemed to be promising was that Wurmple’s evolution was determined based on the weather conditions it was caught in. After all, third generation Pokemon were introduced to Pokemon GO along with an update that added a dynamic weather system to the game. It would make sense that this new feature would play a role in Wurmple’s evolution, but that doesn’t appear to be the case either.
With many of the top theories surrounding Wurmple’s evolution debunked, it seems safe to say that the creature’s evolution is random. If so, it’s actually somewhat fitting and true to the creature’s nature, as Wurmple’s evolution was essentially random in Pokemon Ruby and Sapphire as well.
Pokemon GO is available now for iOS and Android mobile devices.
