Tentacool
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.

Heartgold

When the tide goes out, dehydrated TENTACOOL remains can be found washed up on the shore.

Soulsilver

It drifts aimlessly in waves. Very difficult to see in water, it may not be noticed until it stings.
