Tentacool
Ruby

TENTACOOL’s body is largely composed of water. If it is removed from the sea, it dries up like parchment. If this POKéMON happens to become dehydrated, put it back into the sea.

Sapphire

TENTACOOL absorbs sunlight and refracts it using water inside its body to convert it into beam energy. This POKéMON shoots beams from its crystal-like eyes.

Emerald

Its body is almost entirely composed of water. It ensnares its foe with its two long tentacles, then stabs with the poison stingers at their tips.

Firered

Its eyes are as transparent as crystals. From them, it shoots mysterious beams of light.

Leafgreen

Drifts in shallow seas. Anglers who hook them by accident are often punished by their stingers.
