Okay, I admit I didn't see the 2017 My Little Pony movie. Some of the scenes I did see in the previews, though, were very memorable. The one that stood out for this month was when the Mane 6 visited Seaquestria and were turned into seaponies. This was an especially pleasant surprise for Fluttershy, because she could now get to know the unique creatures in this undersea kingdom.
Yes, I decided to reserve this fanart drawing for the Mermay event. Hope you like it!

This is cool!
Have you ever seen the original SeaPonies (Gen I)? They even have their own theme song.
