For today's post I will be talking about why the Pokémon Slowpoke becomes smarter when it evolves into a Slowking. The Pokémon Slowpoke is generally known for being a very slow Pokémon, and it usually doesn't move very much. It is often a very forgetful Pokémon too. However, this all changes when it evolves into Slowking. After it evolves, it becomes extremely intelligent. It was even shown in Pokémon The Movie 2000 that one Slowking learned how to speak. It's also said to have intelligence as high as an award-winning scientist as well. This happens because the Shellder on its head releases a toxin into it every time it bites down on Slowking's head. Even though this toxin makes it very smart, Slowking will forget all it has learned if the Shellder lets go of its head. Oddly enough, it only seems to gain this intelligence when a Shellder bites its head, since it will still be lazy and forgetful if the Shellder bites onto its tail and it evolves into Slowbro instead.
