It looks like a certain Grass/Poison-type Pokémon that started out in Generation V could be returning in part one of the upcoming Pokémon Sword and Shield expansion.

Twitter user and Pokémon fan @mattyoukhana_ appears to have discovered evidence of the mushroom-like pocket monster Amoonguss in the latest trailer for the game, which was aired earlier this week. This is the evolution of Foongus.

You can see it around the 2:53 mark in a brief shot featuring the expansion logos:

And this is the Pokémon

As this particular clip appears on the Isle of Armor side of the screen, there's a theory this Pokémon will show up in part one of the Expansion Pass later this month.

The possible return of this 'mon is considered to be a big deal by the competitive scene, as it's become a staple of the Pokémon Video Game Championships over the years. Some replies to the original tweet jokingly suggested it was "the return of the king" whereas other responses weren't so happy about the discovery.
