Hypno, a Hypnosis Pokémon. It carries a pendulum-like device and performs hypnotic attacks.
– Ash’s Pokedex
Hypno has such a “I see what you did thar” look. I wonder if the pendulum-like device it carries is part of its body. Unlike the bone and the stick carried by Cubone and Farfetch’d, Hypno’s pendulum was never made into an item.
