Horsea frist apperars in the episode called Teantacool and Tentacruel. It tries to warn Misty and the gang that there are dangerous Tentacools and Tentacruels by drawing pictures with it's black ink.
Later on, Misty gets to keep Horsea. We don't see Horsea much more after this. Because she leaves at the Cerulean town gym with her sisters.
Horsea is one of those annoyingly cute Pokemon whom you just can't help but love! It has a really cute look and one of those cries that you just can't resist! Horsea Horsea. I love it's cry.
Handle with care. Horsea is a little fragile. It's good at defense, but that doesn/t mean it can deal with a major attack.
It's been knowen to shoot down bugs from the surface of the water with blusts of ink, so that makes it pretty good against bug elements.
