1988: Colour Change Baby Sea Ponies
SEASHORE
Aqua baby sea pony with white mane, orange fin paint. orange and blue fish float.
The colours shown above are correct for Seashore in her original state, though when new she would change colour in warm water. I have seen numerous Seashores on the market whose colours have given way completely, leaving her a snotty beige colour - and this makes her easily confused with Foamy.
Therefore the only way to know for sure if your pony is Seashore is to check her finpaint, which should be ORANGE.
Seashore was sold worldwide.
