Another trailer for Pokemon Sun and Moon has posted today on YouTube. This trailer mostly showcases evolved forms for some of the new Pokemon being introduced in these games, and also introduces two new human characters as well as the Alolan variants of Grimer and Muk. Take a look.
According to the info on serebii.net, the reason for Grimer and Muk's transformations is because originally Grimer had been imported from other regions to eat the excess garbage produced by the people of Alola. The steady diet of this garbage has caused Grimer and Muk to produce crystalized toxins on their bodies, and for toxins that were already present in Muk's body to go through a chemical change.
That pretty much does it for this update. I'll try to bring in more information as it comes.
