Drifts in shallow seas. Anglers who hook them by accident are often punished by stinging acid.
Blue
Yellow
It can sometimes be found all dry and shriveled up on a beach. Toss it back into the sea to revive it.
Gold
When the tide goes out, dehydrated TENTACOOL remains can be found washed up on the shore.
Silver
It drifts aimlessly in waves. Very difficult to see in water, it may not be noticed until it stings.
Crystal
As it floats along on the waves, it uses its toxic feelers to stab anything it touches.
Ruby
TENTACOOL's body is largely composed of water. If it is removed from the sea, it dries up like a 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 stinging acid.
Diamond
Its body is virtually composed of water. It shoots strange beams from its crystal-like eyes.
Pearl
It drifts in sea currents. Countless fishermen are hurt by its poison stingers.
Platinum
Because its body is almost entirely composed of water, it shrivels up if it is washed ashore.
Stadium 1
Fires beams of light from its clear eyes. Floats around in shallow waters and may sting unwary anglers.
Stadium 2
When the tide goes out, dehydrated TENTACOOL remains can be found washed up on the shore.
