Chinchou is a small, round, blue fish-like Pokémon with a pair of tiny white fins and two small blue feet. It has two antennae that are positioned on its rear like two tails. There is a yellow teardrop-shaped orb at the end of each. Chinchou's eyes have unique pupils that are shaped like plus signs.
Chinchou charges up its electric attacks by absorbing energy through its two antennae.
Chinchou, the Angler Pokémon, have the ability to conduct electrical currents from their two tentacles which flow positive from one end and negative to the other. Chinchou can also communicate underwater by flashing its tentacles.
This concludes the entries from the original series.
Pokémon Pinball: Ruby & Sapphire: Chinchou are the main bumpers on the Ruby Field. Hitting a nearby button will change the formation from three floating in place, to three moving around, to just the one moving around. They will occasionally disappear and be replaced by Lotad or Whiscash.
This Pokémon was unavailable prior to Generation II.

Chinchou's name is a play on 提灯 chōchin, lantern. Its Japanese name is also a corruption of chōchin. Also, the チョウチンアンコウ chouchin-anko is the name of the footballfish, a deep-sea fish similar to Lanturn. It is also interesting to note that chouwa is the Japanese word for harmony, since this would describe the balance of Chinchou's water and electric types.
