Zapfish



Zapfish (Japanese: デンチナマズ denchinamazu) are creatures that appear in Splatoon ' s Hero Mode. The player must rescue one at the end of every level in order to proceed in the story. There are two types of Zapfish in the game. A normal Zapfish is a regularly tiny one at approximate size of an Inkling Head and generates some power. On the other hand, a more powerful Zapfish known as the Greater Zapfish provides more electricity enough to light up Inkopolis. Normal Zapfish are held captive by bosses such as the Octo-Stomp while the Greater Zapfish is held by Dj Octavio

Description
Zapfish are the main power source of Inkopolis. They were stolen and taken to Octo Valley, a hidden underground base used by the Octarians. Agent 3, under the guidance of Cap'n Cuttlefish, must rescue all the Zapfish in order to restore Inkopolis' power supply. A Zapfish is found near the conclusion of every level in Hero Mode, enclosed in a glowing sphere and sitting on a light bulb-esque pedestal. Players must shoot the sphere with Ink until it bursts, releasing the fish.

Appearance
Zapfish appear similar to a cross between a small fish and a light bulb's filament. They seem to have a large head with two small eyes, two nostrils, and a big pair of orange lips. Below the head is a smaller, yellow body. When a Zapfish is successfully rescued from a level, upon replaying that level, the Zapfish appears to be replaced by a cloth-like dummy.

Trivia

 * Zapfish in the Octarians' spheres are surrounded by electrical charges, likely indicating that they are generating power for Octo Valley.
 * The Japanese name "Denchi Namazu" literally means "Catfish Battery."  Similar to electric eels, some catfish produce an electrical discharge to defend themselves.
 * Inkopolis is powered by a single gigantic, ancient Zapfish called the Great Zapfish.
