The Pokemon Company has released another new trailer for the next pair of 3DS Pokemon games, Pokemon Ultra Sun and Ultra Moon. This video provides a look at more of the new features developer Game Freak has added to the upcoming titles, including another brand-new Legendary Pokemon.

Along with the previously revealed UB-Burst and UB-Assembly, Ultra Sun and Ultra Moon will feature at least one more completely new Ultra Beast, this one codenamed UB-Adhesive. This mysterious and adorable new Pokemon is a Poison-type and is said to be able to understand humans if it spends enough time among them. You can see screenshots of it below.
