Stats & Training
Tentacool's spread isn't flashy. Sp. Def leads, Defense trails, 1 stats clear the bar. Common in the wild and worth 1 Sp. Def EV, on a slow 1.25M XP grind.
It drifts through the sea searching for prey. Its poisonous tentacles break off sometimes, but after a while, they grow back.
Its body is 99% water. The remaining 1% contains the organ that makes its poison.
Tentacool Weakness
Tentacool is weak to Electric, Ground, and Psychic. 8 resistances give it solid defensive coverage on top of that. Tentacool's special bulk (base 100 Sp.Def) helps absorb special-type weaknesses, though physical moves exploit the lower Defense.
