The Seaponies are brightly colored seahorse-like creatures who dwell in the rivers and lakes of Dream Valley. They love underwater polo and can perform elaborate songs and dance numbers. They were first released in 1983 and only appeared in the two Generation 1 Specials. The Seaponies are based on the Hippocamp, a mythological creature shared by Phoenician and Greek mythology. A sub-line of the Seaponies called Baby Seaponies debuted later in 1985. The sea ponies did not appear in My Little Pony 'n Friends season 2 despite the fact a new line of sea sparkle baby sea ponies were released that year.
Rescue at Midnight Castle and Escape from Catrina[]
The Seaponies First appeared in the Pilot episode called Rescue at Midnight Castle. The Seaponies save Megan and Applejack from the sea while singing "The Seaponies Song (also credited as Seaponies and Call upon the Seaponies."
The 3 Lead Ponies, Seawinkle, Sealight and Wavedancer help the 2 while singing about if and when they needed their help again.
The sea ponies are next seen in Escape from Catrina, first playing ball with the little ponies and then singing at the costume ball they’re holding, singing their trademark shoo be doo.
My Little Pony 'n Friends[]
Baby sea ponies
In the series, it is only baby sea ponies who appear, which are much smaller than the adults. Baby sea ponies use floats, though they don’t appear to actually need them to help with swimming. It is unclear if the adult sea ponies are simply offscreen characters or if the six onscreen baby sea ponies have been left under the care of the ponies at Paradise Estate. Due to the sea ponies being aquatic they usually take a back seat in the stories compared to the other three types of ponies, though on occasion they do help out as shown in The Ghost of Paradise Estate when they help transport Megan and some others in giant air bubbles.
The sea ponies natural habitat is water, being able to survive it at various temperatures, Surf Rider and Sea Shimmer seemed unbothered by the freezing cold water in baby its cold outside and only by being trapped underneath the ice. When sea ponies are taken out of water they will become weak and sick, when all the lakes and rivers dry up in the golden coins the baby sea ponies nearly die before it begins raining again. The sea ponies appear to live in all the waters of Dream Valley and don’t appear to have a set home other than the numerous lakes, ponds and rivers they inhabit and play in.
Whitecap and Sea Mist singing
The sea ponies are a lot stronger than they look, they are able to lift things that others would struggle with like a chest of coins and Baby Ribbon on one occasion. They also like to play underwater polo and volleyball in the water, but they appear to love singing their song Shoo-bee-doo, shoo-shoo-bee-doo, shoo-bee-doo, shoo-shoo-bee-doo!
