Tentacool is technically a pre-evolution of Tentacruel, but it holds its own in formats where Eviolite is allowed. Only weak to Electric, Ground, and Psychic. Known as the Jellyfish Pokemon. Flexible enough to run physical or special sets.
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.
They fire beams from the glassy, magenta orbs that resemble eyes atop their heads, and they drift in shallow seas. During low tide, they can sometimes be found on beaches, desiccated.
Tentacool Weakness
GoodTentacool is weak to Electric, Ground, and Psychic-type moves. 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.
Tentacool evolves into Tentacruel. It's a two-stage chain with the method shown below. A small partner pool for breeding via one egg group. Eggs are average hatch time. Evolving adds up to 180 stat points total.
How to Evolve
Breed Tentacool easily with 4 breeding partners from the Water3 egg group.
