Angler

The Angler is an NPC that doesn't sell anything, but rather assigns quests to players. Quest objectives generally involve catching him rare fish from different biomes, for which he dispenses various rewards. When threatened, he will throw Frost Daggerfish at nearby enemies.

The Angler is first encountered randomly sleeping on the sand or on the water surface of an Ocean biome. He will move in when:

Note: The Angler is moveable with a teleporter.
 * You have an empty House available for him.
 * You have talked to him and woken him up.

Completing Quests
Speaking to the Angler and clicking his "Quest" button will display the day's quest. They generally involve Fishing for a particular item. The item will only be catchable during the day when its Quest is in effect.

Once you've caught the required item, speak to the Angler and click "Quest" again. The Quest item in your inventory will be replaced by a reward.

Quest Rewards
After a quest has been completed, the Angler will reward the player with one item and possibly one bait. The item can also take form of Coins.

The chances of all non-decoration/potion items gradually increase with the number of quests finished. For example:
 * At 50 completed quests, chances reach 2x their stated base rate below, eg. items with a 1/40 base chance now have a 1/20 chance.
 * At 100 completed quests, chances reach 4x their stated base rate below, eg. items with a 1/40 base chance now have a 1/10 chance.
 * At 150 completed quests, chances reach 6.67x their stated base rate below, eg. items with a 1/40 base chance now have a 1/6 chance.
 * After the 150th completed quest, the chances permanently reset to their base rates below, as if the player were always on their first quest each time thereafter (this is possibly unintended).

Names
The Angler may have any of the following names:

 * "You saved me! You're awful nice, I could use you... er, I mean, totally hire you to do some awesome stuff for me!"

Trivia

 * The Angler's sprite is unique, as he is a child, and therefore younger than all the others. He is a block shorter than any of the others and is the only child NPC in the game.
 * While most NPCs die via the usual death animation, the Angler simply vanishes in a puff of smoke. He also has a unique death message, instead of " was slain..." it says " has left!" This is most likely due to rating concerns, as depictions of children being killed tend to result in an Adults Only rating from the Entertainment Software Rating Board (ESRB), which would have drastically limited the game's distribution.
 * The sleeping Angler is able to float on Water and Honey.
 * The quest for the Clownfish is a reference to the Pixar movie, Finding Nemo.
 * The quest dialog for the Batfish is a reference the iconic Batman theme song.
 * The quest dialog for the Pengfish is a reference to Superman.
 * Despite his Quest dialog claiming that he will be "Sooo Rich!", the Jewelfish is still worth nothing when sold.
 * The achievement "Fast and Fishious" is a reference to the movie series Fast and Furious.
 * Based on many of his quotes, the Angler seems to be plotting something.
