HORSEA eats small insects and moss off of rocks. If the ocean current turns fast, this POKéMON anchors itself by wrapping its tail around rocks or coral to prevent being washed away.
Sapphire:
If HORSEA senses danger, it will reflexively spray a dense black ink from its mouth and try to escape. This POKéMON swims by cleverly flapping the fins on its back.
Fire Red:
It maintains balance using its tail, which is wound up like a coil. It may spray ink from its mouth.
Leaf Green:
Known to shoot down flying bugs with precision blasts of ink from the surface of the water.
