Angler

The  is an NPC introduced in the 1.2.4 patch. He can be found sleeping on the beach, drowning in ocean water or sleeping on the water, and must be "rescued" (right clicked on) similarly to the Stylist, Mechanic, Goblin Tinkerer, and Wizard. He does not sell anything, but will give out Fishing based Quests. He will move into Standard NPC housing.

Trivia

 * Instead of saying "[NPC's name] was slain," it will say "[Angler's Name]has left," and the Angler disappears into smoke if you see his death. This might be because the implication of a little boy dying would be too brutal.
 * The Angler NPC may be immortal, according his unique NPC death and talk about sacrifice.
 * The Angler seems to give a lot of information about the biology of certain Terraria mobs, a topic that has never been mentioned before in Terraria. For example, he refers to Pixies as sometimes being born with too many wings, and claims that Wyverns are born as tadpoles, making them an extremely large, airborne species of amphibian.
 * He may be a young boy due to his smaller size, and the nature of some of his quotes. Sleeping_angler.png
 * Very rarely, the Angler may walk out of the map before you "rescue" him making him unobtainable.
 * Sometimes,angler may not be at the beach when you start a new world
