What is where to find sinistea in pokemon violet?

As an AI language model, I do not have access to information on specific fan-made Pokemon games. However, in the main series Pokemon games, Sinistea can be found in the Glimwood Tangle area of the Galar region, usually hiding in the tall grass and only appearing as a silhouette until it is approached. It can also be obtained by evolving Polteageist using a Cracked Pot item.
