This is Seatide, daughter of Sonata Dusk and Captain Flash Sentry of the Royal Crystal Guard. Seatide is a very sweet and kind young mare, even if she is a bit clueless or ditzy at times, she means well. Seatide, in her pony form, owns a surfboard rental store on the shores of Hoofalulu and teaches fillies and ponies alike how to surf. Although, she tries to keep out of the water in public due to her transformation into a Siren when she hits the water. Her siren form is more or less an aquatic pony, due to her being a hybrid of a pony and a Siren. In her Siren form, she has a long tail, fins along her four hooves, and gills along with fangs and split pupils. In her siren form, she can lure ponies into a trance due to her gem being inplanted on her chest since birth, but she usually only uses this magic to erase the memory of her Siren form.
