Tentacruel has tentacles that can be freely elongated and shortened at will. It ensnares prey with its tentacles and weakens the prey by dosing it with a harsh toxin. It can catch up to 80 prey at the same time.
Tentacruel has large red orbs on its head. The orbs glow before lashing the vicinity with a harsh ultrasonic blast. This Pokémon's outburst creates rough waves around it.
