Greengill

The Greengill is a very common type of fish that makes an appearance in Twilight Princess.

Greengills can be found in any body of water. As the name implies, they are green, and quite small. Link is required to catch two of them at the beginning of the game, as Link must get the fish to lure Sera's cat. Hena is quite fond of Greengills, and has many in her house.
