Two important things here for the delusional people who think that she is a linear stereotype that follows a very strict pattern:

1. She can turn into a seapony. For those who believed that the water can help you at avoiding her,she has discovered the existence of the magical necklace and she can master the transformation seamlessly as well as her swimming abilities. Don't believe that she simply stick woth her alicorn form. She can go anywhere and no location is free of her presence. The environment doesn't matter to her in the slightest.

2. She is not a simple nightly entity,she is an organic pony after all. What do I mean? She doesn't just show up at night. There have been archives and reports that reveal her existence at daytime and watch out,very comfortably during her stay at the beach. She doesn't become disintegrated because of the sunrays. Remember that Luna went to the beach in Between Dark and Dawn...well, her fanatism for such place and getting exposed to the sun remain quite the same actually. For those fools who are waiting for the sun to show up and magically stop the counter because of such phenomenon, you are going to run into a very shocking irony. You don't end the game by just waiting for the sun to rise, contrary to your average horror experience.

Consider yourselves warned because she is way more versatile than you expect.
