Eskimo

The Eskimo is a rare type of wandering villager that spawns in the tundra and snowy taiga biomes. They often are seen over ice-fishing holes and are seen fishing continuously. When a player walks by they will run to the player and offer to trade them a golden trout if the player can fetch them four cod and five salmon. When the player gives them what they wanted the eskimo gifts the player the golden trout (which when eaten gives you regeneration, jump boost, speed, luck, haste, and strength for 10 minutes).

Behaviour
The Eskimo villager is often seen with a “shivering” animation and is seen fishing continuously but is seemingly failing until he sees a player walking by asking if they can fetch him fish, gifting in return the golden trout. Eskimoes at night go to their igloo which is not too far away.

Eskimoes are NPCs and if the player leaves the area after they get the golden trout they will most likely despawn.
