Angler

The Angler is an NPC encountered, at first, sleeping in the sand of an Ocean biome. He will move in when: He doesn't sell anything, but rather quests the player to find him rare fish from different biomes in rewards for treasure. Once you collect the fish he asks you for, he won't give out anymore quests until the next in-game day.
 * You have an empty House available for him.
 * You have talked to him and woken him up.

Names
The Angler may have any of the following names: Billy, Charles, Matty, Danny, Timmy, Bobby

Trivia

 * His character is very unique, as he seems to be a child, because he is a block shorter than all other NPC's and players, and talks a bit like one. If that is the case, he's the only child NPC in the game. He's also the first NPC to do quests.
